class=\"wp-block-heading\">What Is the Difference Between Aluminum Strength and Stiffness?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Strength and stiffness are two properties that must be evaluated separately when selecting an aluminum alloy. Strength determines when a part undergoes permanent deformation or fracture under load and is commonly expressed by yield strength and tensile strength. Stiffness determines the amount of elastic deformation produced under load and mainly depends on the elastic modulus and the cross-sectional geometry of the part.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common aluminum alloys typically have an elastic modulus of approximately 69\u201372 GPa. Although <a href=\"https:\/\/weldomachining.com\/ja\/6061-t6-aluminum-strength\/\" data-type=\"post\" data-id=\"11685\">6061-T6 <\/a>\u305d\u3057\u3066 <a href=\"https:\/\/weldomachining.com\/ja\/7075-t6-aluminum\/\" data-type=\"post\" data-id=\"11860\">7075-T6<\/a> differ significantly in strength, their elastic moduli are similar. This means that replacing 6061 with 7075 under the same dimensions and loading conditions can increase load-bearing capacity, but it will not substantially reduce the elastic deflection of the part.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If excessive deflection is the main issue in a bracket, beam, mounting plate, or thin-walled housing, simply selecting a stronger material will not solve the problem at its source. More effective methods include increasing the section thickness, shortening the cantilever length, adding reinforcing ribs, optimizing support locations, or changing the cross-sectional geometry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Material selection can be evaluated according to the following principles:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Preventing permanent deformation:<\/strong> Focus on yield strength and verify it against the actual load, safety factor, and locations of stress concentration.<\/li>\n\n\n\n<li><strong>Preventing fracture:<\/strong> Focus on tensile strength, fracture toughness, fatigue performance, and the loading direction of the part.<\/li>\n\n\n\n<li><strong>Limiting elastic deformation:<\/strong> Focus on elastic modulus, area moment of inertia, support configuration, and part geometry.<\/li>\n\n\n\n<li><strong>Controlling weight:<\/strong> Compare the specific strength of the materials and the final part weight after meeting stiffness and strength requirements.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, selecting an aluminum alloy for a custom part should not be based solely on the grade with the highest strength. When structural stiffness is insufficient, the part geometry should be optimized first. When load-bearing capacity is insufficient, an alloy and temper with higher yield strength and better fatigue performance should be selected.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do Product Form and Temper Affect Aluminum Strength?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The mechanical properties of the same aluminum alloy grade cannot be treated as identical when it is supplied as plate, extrusion, bar, forging, or casting. The production method changes the grain structure, deformation direction, residual stress, and internal defect level of the material. Therefore, a drawing should specify more than simply \u201c6061\u201d or \u201c7075\u201d; it should also define the product form, temper, and applicable standard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Sheet and plate:<\/strong> Rolling creates a distinct material orientation. Strength, elongation, and fracture toughness vary among the longitudinal, long-transverse, and short-transverse directions. The properties at the center of a thick plate may also be lower than those near the surface. For large load-bearing parts, the minimum properties specified by the applicable standard must be verified according to plate thickness and loading direction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Extruded profiles:<\/strong> Extrusions are suitable for producing long parts with a constant cross-section, but wall thickness, cross-sectional complexity, and quench-cooling conditions affect the final properties. The properties of 6061-T6 and 6061-T6511 extrusions cannot be taken directly from plate data. The appropriate extrusion standard must be used to confirm their properties during procurement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u935b\u9020\u54c1\uff1a<\/strong> Forging improves material density and directs the metal flow along the part profile, making it suitable for highly loaded connectors, aerospace structural components, and high-fatigue parts. Forging properties are directly related to forging direction, forging ratio, heat treatment, and specimen orientation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\u92f3\u7269\uff1a<\/strong> Cast aluminum alloys can form complex structures, but porosity, shrinkage, and oxide inclusions reduce fatigue strength and elongation. Pressure-containing parts and critical structural components must define the casting grade, heat-treatment condition, internal defect acceptance criteria, and nondestructive testing requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Temper also significantly changes material performance:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>T6:<\/strong> Solution heat-treated and artificially aged to provide high strength. It is a common supply condition for 6061 and 7075 parts.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/weldomachining.com\/ja\/2024-t351-vs-6061-t651\/\" data-type=\"post\" data-id=\"14379\">T651<\/a>:<\/strong> Based on the T6 temper with residual stress relieved by stretching. It is more suitable for thick plate and precision CNC parts that require extensive material removal.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/weldomachining.com\/ja\/2024-t351-vs-6061-t651\/\" data-type=\"post\" data-id=\"14379\">T6511<\/a>:<\/strong> Commonly used for extruded bars and profiles, with stress relieved by stretching followed by straightening.<\/li>\n\n\n\n<li><strong>T73, T7351, and T7451:<\/strong> Overaged tempers that reduce peak strength but improve the stress-corrosion resistance and dimensional stability of high-strength aluminum alloys such as 7075.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Engineering drawings should specify the \u201calloy grade + temper + product form + material standard.\u201d For example, even though 6061-T651 plate and 6061-T6 extrusion share the same alloy grade, their guaranteed properties, residual stress levels, and machining stability are not identical.<\/p>\n\n\n\n<figure

class=\"wp-block-heading\">How Can Deformation Be Controlled During Machining?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Aluminum alloys have a relatively low elastic modulus and high thermal conductivity, making them sensitive to residual stress, clamping force, and material-removal sequence. Thin-walled housings, long plates, deep-pocket parts, and components subjected to extensive one-sided milling are prone to warping, twisting, wall-thickness variation, and hole-position deviation during machining.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Deformation mainly results from the following factors:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Residual stress in the raw material:<\/strong> Rolling, extrusion, quenching, and straightening generate residual stresses within the material. When CNC machining disrupts the original stress balance, the part deforms in the direction of stress release.<\/li>\n\n\n\n<li><strong>Asymmetrical material removal:<\/strong> Removing a large amount of material from only one side of a plate causes uneven stress release between the upper and lower surfaces, resulting in part bending.<\/li>\n\n\n\n<li><strong>Excessive clamping force:<\/strong> Thin-walled areas may be flattened or straightened while clamped. After the fixture is released, the part springs back, causing dimensional and geometric tolerances to fall outside specification.<\/li>\n\n\n\n<li><strong>Cutting heat and tool condition:<\/strong> Tool wear, poor chip evacuation, or unsuitable cutting parameters increase localized temperature and cutting forces, causing thermal deformation and surface tearing.<\/li>\n\n\n\n<li><strong>Insufficient structural rigidity:<\/strong> Deep pockets, narrow ribs, long overhangs, and thin-walled structures are prone to vibration or tool deflection under cutting forces, resulting in uneven thickness and profile errors.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Precision aluminum parts should be machined in stages. Rough machining is performed first while leaving a uniform allowance. The part is then allowed to stabilize or undergoes stress-relief treatment when necessary, enabling part of the internal stress to dissipate. The machining datum is subsequently re-established before semi-finishing and finish machining. For flat parts, material should be removed symmetrically from opposing surfaces whenever possible to avoid machining directly to the final dimensions in a single operation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thin-walled parts require low-deformation fixtures, soft jaws, or dedicated support structures, with clamping force applied to rigid areas. Sharp cutting tools, stable cutting parameters, and effective chip evacuation must also be maintained to prevent cutting forces from increasing as the tools wear.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For parts requiring high dimensional stability, low-residual-stress materials in T651, T6511, T7351, or T7451 tempers should be prioritized. Final inspection must be performed after the part has been completely released from the fixture and returned to a stable temperature. Otherwise, the measurement results will not represent the part in its free state.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/weldomachining.com\/wp-content\/uploads\/2026\/07\/6061-t6-aluminum-part-with-Hard-Anodizing.webp\" alt=\"\u30cf\u30fc\u30c9\u30a2\u30eb\u30de\u30a4\u30c8\u51e6\u7406\u304c\u65bd\u3055\u308c\u305f6061-T6\u30a2\u30eb\u30df\u30cb\u30a6\u30e0\u88fd\u90e8\u54c1\" class=\"wp-image-11970\" style=\"width:505px;height:auto\" srcset=\"https:\/\/weldomachining.com\/wp-content\/uploads\/2026\/07\/6061-t6-aluminum-part-with-Hard-Anodizing.webp 800w, https:\/\/weldomachining.com\/wp-content\/uploads\/2026\/07\/6061-t6-aluminum-part-with-Hard-Anodizing-300x300.webp 300w, https:\/\/weldomachining.com\/wp-content\/uploads\/2026\/07\/6061-t6-aluminum-part-with-Hard-Anodizing-150x150.webp 150w, https:\/\/weldomachining.com\/wp-content\/uploads\/2026\/07\/6061-t6-aluminum-part-with-Hard-Anodizing-768x768.webp 768w, https:\/\/weldomachining.com\/wp-content\/uploads\/2026\/07\/6061-t6-aluminum-part-with-Hard-Anodizing-12x12.webp 12w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Why Does Welding Reduce the Strength of Aluminum Alloys?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The localized high temperature generated by welding changes the microstructure of the weld and heat-affected zone in aluminum alloys. For aluminum alloys strengthened through heat treatment or work hardening, welding disrupts the original strengthening effect. Therefore, the design strength of a welded joint cannot be based directly on the T6, T651, or H32 properties of the base material.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>6xxx-series aluminum alloys:<\/strong> Alloys such as <a href=\"https:\/\/weldomachining.com\/ja\/6061-t6-aluminum-strength\/\" data-type=\"post\" data-id=\"11685\">6061-T6<\/a> are strengthened by magnesium-silicide precipitates. The welding thermal cycle dissolves or coarsens these strengthening precipitates in the heat-affected zone, creating a distinct softened region. Joint strength is normally controlled by the heat-affected zone rather than the unaffected base material.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>5xxx-series aluminum alloys:<\/strong> Materials such as 5052-H32 and 5083-H116 primarily obtain their strength through work hardening. Welding heat causes recovery or localized annealing in the heat-affected zone, reducing hardness and strength. The welded joint can no longer be designed using the full strength of the original H temper.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2xxx- and 7xxx-series high-strength aluminum alloys:<\/strong> These materials are more sensitive to hot cracking, porosity, strength reduction, and stress-corrosion cracking during welding. Alloys such as 2024 and 7075 are generally unsuitable for conventional fusion-welded structures. Mechanical fastening, integral CNC machining, forging, or fully validated solid-state joining processes are more suitable for critical load-bearing components.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Weld-strength control must be addressed during the design stage rather than added after the part has been manufactured. Drawings should clearly specify the welding method, filler-wire grade, joint configuration, weld dimensions, permissible defects, inspection method, and whether post-weld heat treatment is required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Post-weld heat treatment can restore part of the strength of heat-treatable aluminum alloys. However, repeated solution heat treatment and aging can cause dimensional changes, deformation, and additional costs, and not every large or complex assembly is suitable for complete heat treatment. Welded structures should therefore be calculated using the allowable strength of the welded joint, with the heat-affected zone positioned in a low-stress area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When accepting custom welded aluminum parts, inspection should cover not only dimensions and appearance but also weld formation, porosity, cracks, lack of fusion, and softening in the heat-affected zone. Critical load-bearing assemblies require penetrant testing, radiographic testing, or mechanical-property verification in accordance with the drawing and applicable specifications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u30a2\u30eb\u30df\u30cb\u30a6\u30e0\u306e\u5f37\u3055\u306e\u307e\u3068\u3081<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\u3053\u306e\u8a18\u4e8b\u3067\u306f\u3001\u30a2\u30eb\u30df\u30cb\u30a6\u30e0\u3068\u30a2\u30eb\u30df\u30cb\u30a6\u30e0\u5408\u91d1\u306e\u4e3b\u8981\u306a\u6a5f\u68b0\u7684\u6027\u8cea\u306b\u7126\u70b9\u3092\u5f53\u3066\u3001\u964d\u4f0f\u5f37\u3055\u3001\u5f15\u5f35\u5f37\u3055\u3001\u5727\u7e2e\u5f37\u3055\u3001\u75b2\u52b4\u5f37\u3055\u3001\u305b\u3093\u65ad\u5f37\u3055\u306e\u5b9a\u7fa9\u3001\u4ee3\u8868\u7684\u306a\u5024\u3001\u5de5\u5b66\u7684\u610f\u7fa9\u3092\u4f53\u7cfb\u7684\u306b\u8aac\u660e\u3057\u307e\u3059\u3002\u307e\u305f\u30016061\u30017075\u30015052\u3068\u3044\u3063\u305f\u4e00\u822c\u7684\u306b\u4f7f\u7528\u3055\u308c\u308b\u5408\u91d1\u306e\u6027\u80fd\u306e\u9055\u3044\u3092\u3001\u69d8\u3005\u306a\u71b1\u51e6\u7406\u6761\u4ef6\u4e0b\u3067\u6bd4\u8f03\u3057\u3066\u3044\u307e\u3059\u3002\u9069\u5207\u306a\u30a2\u30eb\u30df\u30cb\u30a6\u30e0\u6750\u6599\u3092\u9078\u629e\u3059\u308b\u5834\u5408\u3001\u307e\u305f\u306f\u30ab\u30b9\u30bf\u30de\u30a4\u30ba\u3055\u308c\u305f\u52a0\u5de5\u30bd\u30ea\u30e5\u30fc\u30b7\u30e7\u30f3\u304c\u5fc5\u8981\u306a\u5834\u5408\u306f\u3001\u304a\u6c17\u8efd\u306b\u304a\u554f\u3044\u5408\u308f\u305b\u304f\u3060\u3055\u3044\u3002 <a href=\"https:\/\/weldomachining.com\/ja\/%e3%81%8a%e5%95%8f%e3%81%84%e5%90%88%e3%82%8f%e3%81%9b\/\" data-type=\"page\" data-id=\"14\">\u30b3\u30f3\u30bf\u30af\u30c8 <\/a>\u79c1\u305f\u3061\u306b\u3068\u3063\u3066 <a href=\"https:\/\/weldomachining.com\/ja\/%e3%83%95%e3%82%a1%e3%82%a4%e3%83%ab%e3%82%a2%e3%83%83%e3%83%97%e3%83%ad%e3%83%bc%e3%83%89\/\" data-type=\"page\" data-id=\"843\">\u5c02\u9580\u7684\u306a\u30a2\u30c9\u30d0\u30a4\u30b9\u3068\u8fc5\u901f\u306a\u898b\u7a4d\u3082\u308a<\/a>\u2014\u79c1\u305f\u3061\u306f\u3001\u304a\u5ba2\u69d8\u306e\u30d7\u30ed\u30b8\u30a7\u30af\u30c8\u306b\u52b9\u7387\u7684\u3067\u4fe1\u983c\u6027\u306e\u9ad8\u3044\u30bd\u30ea\u30e5\u30fc\u30b7\u30e7\u30f3\u3092\u63d0\u4f9b\u3059\u308b\u3053\u3068\u306b\u5c3d\u529b\u3057\u3066\u3044\u307e\u3059\u3002.<\/p>","protected":false},"excerpt":{"rendered":"<p>Aluminum alloy, as one of the most commonly used machining materials, is widely seen in CNC machining, aluminum extrusion, and sheet metal fabrication factories.
