5086 Aluminum

Alro stocks 5086 - an aluminum alloy with the primary alloy element being magnesium. It is not strengthened by heat treatment, instead becoming stronger due to strain hardening, or cold mechanical working of the material. Since heat treatment doesn't strongly affect the strength, 5086 can be readily welded and retain most of its mechanical strength. The good weldability and corrosion properties in seawater make 5086 extremely popular for vessel gangways, and boat/yacht hulls. It is considered a sistyer alloy to Aluminum 5083 with comparable characteristics but slightly less strength.
