Anodized Multipurpose 6061 Aluminum Hex Bars

Yield Strength: 35,000 psi
Hardness: Not Rated
Temper: T6511
Fabrication: Extruded
Specifications Met: ASTM B221

A hard-anodized coating forms a bond with the aluminum surface to improve wear and corrosion resistance. It also makes the surface nearly as hard as case-hardened steel, so these hex bars are more difficult to machine than uncoated 6061 hex bars. The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant.

High-Strength 7075 Aluminum Hex Bars

Yield Strength: 56,000 psi
Hardness: Brinell 125 (Medium)
Temper: T7351
Fabrication: Cold Drawn
Specifications Met: ASTM B211, SAE AMS-QQ-A-225/9

Originally developed for aircraft frames, uses for 7075 aluminum now include shafts, gears, and other high-stress parts. It is often used as a replacement for 2024 aluminum because it’s stronger and provides similar performance in all other aspects.

High-Strength 2024 Aluminum Hex Bars

Yield Strength: 47,000 psi
Hardness: Brinell 120 (Medium)
Temper:
1/4" wd.: T4
All other sizes: T351
Fabrication: Cold Drawn
Specifications Met: ASTM B211

While 2024 aluminum was initially designed for structural components in aircraft, it's now widely used when a high strength-to-weight ratio is needed, such as for gears, shafts, and fasteners. It offers similar performance to 7075 aluminum, but it’s not as strong.
