AZ80A Extruded Magnesium Alloy

AZ80A is a high-performance, low-density wrought magnesium base alloy composed of aluminium, zinc, and manganese. With a density approximately 30% less than similar aluminium alloys, AZ80A offers significant weight savings for designers. It is specifically engineered for use as CNC machining bar stock, available in various shapes including round, square, rectangular, and custom solid configurations.

This lightweight alloy is available as balls, extruded rods, bars, tubes and profiles to produce components that have strength and ductility in demanding environments, as well as a controlled dissolution rate that will effectively dissolve the component.
