5059 aluminum sheet is a 5 series aluminum-magnesium alloy aluminum sheet that is made stronger by strain hardening or cold machining. It is usually assembled using arc welding, usually MIG (for marine use) or TIG welding. 5059 aluminum alloy has good corrosion resistance and tensile strength. It is a 5 series product with excellent comprehensive performance and is widely used in ships, tankers and other fields.
In marine environments and other corrosive environments, 5059 aluminum alloy exhibits excellent corrosion resistance, which makes it an ideal material for marine structures and shipbuilding. It has been used as a hull material for small aluminum boats or large yachts. 5059 aluminum alloy has obtained China Classification Society (CCS) certification.
The new generation of marine engineering deformed aluminum alloy 5059 aluminum alloy contains higher Si, Fe, Mn and Mg, as well as trace amounts of Zn and Zr elements compared to traditional 5083 aluminum alloy. The performance of 5059 alloy is better than that of 5083 alloy, but the pressure processing and forming performance are slightly inferior.
