High-Strength 2024 Aluminum Z-Bars

Yield Strength: 42,000 psi
Hardness: Brinell 120 (Medium)
Temper: T3511
Fabrication: Extruded
Specifications Met: ASTM B221, SAE AMS-QQ-A-200/3

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. It offers similar performance to 7075 aluminum, but it’s not as strong.
