1.Corrosion resistance and light
weight.
2.The density of magnesium is 1.74g/cm3 which is even lighter
than aluminum 2.7g/cm3, but mechanical strength and chemical
stability are much better than
aluminum. 3.Magnesium can be directly related to
nitrogen, sulfur and halogen such as chemical combination,
including hydrocarbons, aldehydes, alcohols, phenols, amines,
