Aluminum Extrusion:

Materials and Principles:

Using high-purity aluminum (aluminum content ≥99.7%) or general-purpose aluminum alloys (e.g., 6063, 6061) as base materials, standard profiles are produced through the extrusion process. Its core advantages lie in lightweight properties (density only 1/3 that of steel), corrosion resistance (surface oxide film shields against environmental erosion), and high thermal conductivity (thermal conductivity reaches 237 W/m·K).

Other Aluminum Alloy Materials:

Additives: Alloying Elements and Intermediate Alloys

By incorporating elements like magnesium, silicon, copper, zinc, or specialized aluminum intermediate alloys, material properties can be selectively enhanced to meet extreme operational demands.
Commonly used in automotive body sheet metal frames and aluminum window/door frames for home building materials.

High-Toughness Alloys (e.g., 7075)

Added Elements: Zinc, Magnesium, Copper
Performance Enhancements: Tensile strength reaches 572 MPa (approaching structural steel), fracture toughness increases by 30%.

Corrosion-Resistant Alloys (e.g., 5083)

Added Elements: Magnesium, Manganese
Performance Enhancement: Corrosion rate below 0.01 mm/year in seawater environments; weld joint strength retention ≥90%.
Applications: Ship decks, offshore platform supports, chemical storage tanks.

High Thermal Conductivity Alloys (e.g., 1050A)

Added Elements: Pure aluminum matrix + trace iron, silicon
Performance Enhancement: Thermal conductivity increased to 237 W/m·K, surface flatness tolerance ≤0.05 mm.
Application Areas: 5G base station heat sinks, IGBT module substrates, new energy vehicle motor housings.

Process Advantages:

Low Material Waste: Ingenious mold design enables one-step forming of complex cross-sections, achieving material loss rates below 6% (compared to 40% in traditional machining).
Time Savings: Design-to-production cycle reduced to 2-4 weeks; mold costs amount to approximately 20% of die-casting expenses.
