Magnesium alloy can serve as ballistic protection in lightly armored vehicles in which aluminum (AA5083) is typically used. The high specific stiffness of magnesium alloy – 18 times more than steel – also makes it suitable for use in composite armor systems, for example, as a backing plate to a ceramic-faced system.
The recent MIL-DTL 32333 specification for magnesium alloy AZ31B-H24 ballistic armor plate not only provides troops a lighter-weight protective solution in the field, it also improves mobility and fuel efficiency of military hardware. Used either as stand-alone armor plate or in conjunction with other materials in clad or composite form, magnesium alloy gives materials engineers a strong, durable, lighter-weight design option compared to heavier traditional armor materials. Our Elektron®WE43-T5 plate alloy is being developed for incorporation into the magnesium armor plate specification when ballistic testing is completed in conjunction with the U.S. Army Research Laboratory (USARL).
