Features of 7A04 aluminum bar

• High strength (tensile strength can reach 530 MPa), good heat treatment strengthening effect, medium plasticity in annealing and new quenching state;
• Unlike hard aluminum, the corrosion resistance in artificial aging state is better than that in natural aging state, and the natural aging process is slow, and it takes 3 months to reach the aging hardening peak, so 7A04 is used in the quenching artificial aging state;
• Its disadvantages are low organizational stability, low low-frequency fatigue strength, and a tendency to stress corrosion cracking;
• The alloy has good spot welding weldability, poor gas welding, good machinability after heat treatment, but poor machinability after annealing.

Best cooperation fields for 7A04 aluminum bar

Aerospace field: 7A04 aluminum bar is widely used in aircraft structural parts due to its excellent strength and corrosion resistance, such as beam trusses, bulkheads, wing ribs, landing gear, engine brackets and other load-bearing parts as well as bolts, screws and other connecting parts.

Defense industry: 7A04 aluminum bar is widely used in the defense industry to manufacture high-strength, corrosion-resistant armor parts and structural brackets. Its ultra-high strength ensures the stability and reliability of the material in extreme environments.
