More information
Alloy 1581 (5181) is a deformable, non-heat-treatable Al-Mg-Sc alloy containing up to 0.03% Sc, providing greater strength than alloys 5083, 1561, and similar types.
The alloy was developed to enhance the corrosion resistance and weldability of semi-finished products. It can be used in the marine, railway and other industries. A wide variety of use cases in Shipbuilding, Transportation, Rolling Stock and Automotive.
