AZ31B is a wrought magnesium alloy containing aluminum and zinc, widely used in aerospace and automotive applications where light weight and moderate strength are required. The H26 temper (strain-hardened and partially annealed) provides intermediate strength and ductility suitable for sheet and plate applications, with good formability and improved corrosion resistance compared to softer tempers.
