7005 aluminum coil is a high-strength Al-Zn-Mg series aluminum alloy, belonging to the 7000 series. Unlike many other 7000 series alloys, 7005 aluminum can achieve good mechanical strength without complex heat treatment, making it easier to process and weld. It offers an excellent balance of strength, corrosion resistance, and formability, and is widely used in transportation and structural applications.
