AZ31B is a wrought magnesium alloy with good room-temperature strength and ductility combined with corrosion resistance and weldability. AZ31B finds application in wide variety of uses including aircraft fuselages, cell phone and laptop cases, speaker cones and concrete tools. AZ31B can be superformed at elevated temperatures to produce a wide variety of intricate components for automotive uses.

AZ31 is also available as tooling plate which is specially produced to provide a flat plate surface. The production process of AZ31-TP also results in plate with exceptional dimensional stability in machining. This allows for the manufacture of very complex parts but also components which benefit from the dimensional stability such as jigs, fixtures, optical benches, vibration test equipment and inspection gauges.
