Introduction
Magnesium is a silvery-white metal that is principally used as an alloy element for aluminum, lead, zinc, and other non-ferrous alloys. It is ductile and the most machinable of all the metals. Magnesium M1A-F alloy has low to medium strength and good corrosion resistance.
The following datasheet gives an overview of magnesium M1A-F alloy.
