Non-Combustible Magnesium Alloys
Adding 2% of calcium(Ca) by mass to magnesium alloy AM60 results in the non-combustible magnesium alloy AMCa602. The higher oxidation reactivity of Ca causes a coat of calcium oxide to form before Mg ignites. The ignition temperature of the alloy is elevated by 200-300K. Oxygen-free atmosphere is not necessary for machining operations.
