7075 T7 aluminum alloy is one of the most well-known and widely preferred high-strength aluminum alloys. As a zinc-based alloy, 7075 is strengthened with alloying elements such as magnesium and copper. Thanks to the T7 heat treatment temper, its strength is increased while also improving its resistance to stress corrosion cracking. With these properties, it is especially preferred in the aerospace, defense, and automotive industries where lightweight and high strength are simultaneously required.

Although it has high tensile and yield strength, its weldability is limited; therefore, it is generally used in designs where machinability and mechanical properties are prioritized. At the same time, due to its high surface hardness and wear resistance, it is also widely used in mold making, sports equipment, marine applications, and high-performance engineering parts. The 7075 T7 alloy stands out in critical engineering solutions by offering steel-like strength values together with the lightweight advantage of aluminum.
