Magnesium is known to produce the lightest structural components out of all commonly used metals. So, magnesium’s ultra-lightweight is a unique feature.
Magnesium Alloys are-Extremely lightweight,Melted at a low temperature Easily machinable,Costlier than Aluminum & ZincHighly reactive。
Therefore, Magnesium Die Casting–Requires a hot chamber
die casting machine,Has an excellent strength-to-weight ratio,Can retain strength at high temperatures,Has bad corrosion resistance,Has good RFI and EMI shielding properties。
