AM50A AM50B Magnesium alloy plate AM50A-F, AM50 magnesium tooling plate, surface machined, cut to size
Magnesium alloy plate AM50A-F, AM50 magnesium tooling plate, surface machined, cut to size
Mg content calculated as balance. Excellent energy-absorption characteristics and excellent ductility. Applications for die casting alloy in as-cast (F) temper include parts that require good ductility and toughness with reasonable yield and tensile properties (such as automotive wheels).
