Abstract
The present invention relates to a non-combustible magnesium alloy, comprising one of elements of Al at 0.1˜3 wt %, La at 0.1˜3 wt %, Nd at 0.1˜3 wt %, or Y at 0.005˜3 wt %; 0.5˜10 wt % of Ca; and the remainder of conventional magnesium alloy. Alternatively, the present invention entails a non-combustible magnesium alloy comprising 0.005˜4 wt % of multiple additives of two or more types of elements selected from the group consisting of Al, La, Nd and Y; 0.5˜10 wt % of Ca; and the remainder of conventional magnesium alloy. The magnesium alloy of the present invention has high oxidation-resistance, which translates into high manufacturability in air or in the generally non-oxidative atmosphere (SO , Ar, CO , N ). Moreover, in cases of manufacturing various components by re-melting the above alloys, it is possible to melt and cast the same in a certain period of time within the bounds of not breaking the dross layer in air or in the generally non-oxidative atmosphere (SO , Ar, CO , N ). In addition, due to the superior pyrophoric characteristics, spontaneous combustion of the chips accumulated during the mechanical processing can be effectively prevented. Further, the present invention, by not using certain types of gas such as SF , brings about beneficial collateral effects of cost reduction, protection of workers' health, prevention of environmental pollution, etc.
