The magnesium alloy used is unique in terms of improved flame retardancy, strength, processability, etc. As magnesium has 30% lower specific gravity than aluminum, it is expected that the weight of vehicle structures will be drastically reduced. The magnesium alloy is an alloy to which calcium is added to a general-purpose magnesium alloy (Mg – Al type alloy) by several %, thereby allowing melting and casting under standard concitions. Ignition temperature is increased by 200 to 300 ° C.
