About Alloy
Aluminium Alloy 5056 primary constituent is magnesium which gives this non heat treatable alloy its high strength. Due to Alloy 5056 high strength and excellent formability it is used extensively in cold heading applications as well as wire forms and hinge pins. Alloy 5056 also has excellent corrosion resistance and can be used in atmospheres such as salt water where corrosion would normally be a problem with other metals.
