More information
Alloy 1555 is a non-heat-treatable Al-Mg alloy, providing greater strength than alloy 5182, without loss of ductility. It contains 0.02% Sc.
A typical application is high strength automotive deep drawn inner stampings.
The new 7xxx series high-strength alloy with low scandium content is specifically designed for manufacturing forged wheels.
