Aluminum 7075 CNC Machining
7075 aluminum alloy is a cold-treated forging alloy known for its high strength, significantly surpassing that of soft steel. It is one of the strongest commercial alloys available and features a dense structure with excellent corrosion resistance, making it ideal for aviation and marine applications. The alloy exhibits general corrosion resistance, good mechanical properties, and favorable anodic reaction characteristics. Its fine grain structure enhances depth drilling performance and improves tool wear resistance.
Mechanical Properties
Tensile Strength (σb): ≥ 560 MPa
Elongation Stress (σp0.2): ≥ 450 MPa
Elongation Rate (%): ≥ 10
Note: These mechanical properties apply to seamless rods with a specimen size of diameter ≥ 70 mm.
Heat Treatment
7075 aluminum exhibits improved forming properties in the annealed and newly quenched states, with a significant strengthening effect from heat treatment. However, the heat treatment process must be strictly controlled. While the corrosion resistance of 7075 aluminum is relatively poor, it can be effectively protected through cladding with pure aluminum. Welding can lead to crack formation, but with specialized techniques, it can be welded and riveted successfully.
This alloy is widely used in applications that require high strength and weight efficiency, such as aerospace components, military vehicles, and high-stress structural applications.
