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 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.
