7075 Aluminum Flat Bar
7075 aluminum flat bar is a high-strength aluminum alloy that offers steel-like strength while maintaining the lightweight advantages of aluminum. With excellent fatigue resistance and mechanical stability, it is a preferred material for aerospace structural components, high-performance automotive parts, mold bases, and other high-stress structural applications.
Compared with standard aluminum alloys, the tensile strength of 7075 aluminum flat bars exceeds 540 MPa. Tempers such as T73 and T7351 provide enhanced corrosion resistance, making it suitable for harsh environments such as marine, aerospace, and high-humidity applications.
7075 Aluminum Flat Bar Features
Ultra-High Strength
Tensile strength up to 560 MPa, approaching that of high-strength steels.
Strength-to-Weight Ratio
Offers high strength while being much lighter than steel.
Superior Fatigue Resistance
Stable performance under long-term loading and vibration.
Corrosion Resistance
T6 has low corrosion resistance, but the T73/T73511 tempering treatment significantly improves its resistance to stress corrosion cracking (SCC).
Good Machinability
7075 aluminum alloy is suitable for CNC precision machining; T6511 has higher dimensional stability.
Temperature Resistance
7075 aluminum alloy maintains its properties over a wide temperature range, making it suitable for applications requiring high dimensional stability.
Our 7075 aluminum flat bar conform to international standards such as EN 755, ASTM B221, AMS 4126, AMS 4131, AMS 4141. We also provide Material Testing Certificates (MTC). These documents record chemical composition and mechanical properties. They also include dimensional tolerances. Third-party inspection reports are available upon request. This ensures quality assurance for your critical applications.
