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.

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.

Corrosion-Resistant 3000 Series Aluminum Honeycomb Cores

Yield Strength: Not Rated
Hardness: Not Rated
Temper: Not Rated

The honeycomb design provides a higher strength-to-weight ratio than solid sheets. These cores are often used as a lightweight alternative to solid aluminum and also for sound insulation. 3000 series aluminum stands up to outdoor use, as well as exposure to chemicals. It offers a good combination of strength, formability, and weldability.

Corrosion-Resistant 3000 Series Aluminum Honeycomb Panels

Yield Strength: Not Rated
Hardness: Not Rated
Temper: Not Rated

A honeycomb core is bonded between two aluminum sheets for rigidity. These panels offer a higher strength-to-weight ratio than solid sheets, so they're often used as a lightweight alternative to solid aluminum. They're also used for sound insulation. They are painted white and covered with a protective peel-off film. 3000 series aluminum stands up to outdoor use, as well as exposure to chemicals. It offers a good combination of strength, formability, and weldability.

Composite Fiber Aluminum Honeycomb Panels

Yield Strength: Not Rated
Hardness: Not Rated
Temper: Not Rated

An aluminum honeycomb core sandwiched between carbon fiber keeps these sheets strong yet lightweight. The carbon fiber facing gives you the same strength as a honeycomb panel that's entirely made from aluminum but without the weight. Compared to aramid honeycomb panels, these panels have better shear strength. These panels are often used in the automotive and aerospace industry in place of solid aluminum sheets thanks to their high strength-to-weight ratio.
