Common Aluminum Grades for CNC Machining

Common 2xxx–7xxx alloys and tooling plate arranged for faster material comparison.

Series & Common GradesKey CharacteristicsTypical Applications
2xxx Series 2011 · 2014 · 2017 · 2024 · 2219 · 2618 High strength, good fatigue resistance and strong machinability; lower natural corrosion resistance. Aircraft fittings, fasteners, gears and precision structural parts.
3xxx Series 3003 · 3004 · 3105 Good formability, corrosion resistance and weldability with moderate strength. Covers, tanks, housings, panels and formed components.
5xxx Series 5052 · 5083 · 5086 · 5754 Strong corrosion resistance, good weldability and stable performance in marine environments. Marine parts, tanks, enclosures and welded structures.
6xxx Series 6005 · 6061 · 6063 · 6082 · 6262 Balanced strength, machinability, corrosion resistance and anodizing response. Frames, housings, brackets, fixtures and general precision parts.
7xxx Series 7005 · 7020 · 7050 · 7075 · 7085 Very high strength and fatigue resistance for highly loaded components. Aerospace structures, shafts, tooling and high-load supports.
Cast Tooling Plate MIC-6 Stress-relieved cast plate with stable flatness and predictable machining behavior. Jigs, fixtures, base plates, tooling and low-stress precision structures.

Specify alloy and temper on the drawing because heat treatment and product form change final performance.

Aluminum Machining FAQ

Material and Process Questions

Should I choose 6061 or 7075 aluminum?

Choose 6061 for balanced cost, corrosion resistance and finishing. Choose 7075 when higher strength is the priority.

How do you reduce aluminum part distortion?

Use stable stock, balanced material removal, controlled clamping, suitable toolpaths and final inspection after machining.

Which finish is best for aluminum parts?

Anodizing is common for corrosion and wear; blasting, powder coating and plating serve different cosmetic or functional needs.
