At present, the mainstream materials are still steel and aluminum alloy, which is difficult to meet the requirements of lightweight, rationalization and environmental protection of automobiles in 2 1 century.

Therefore, magnesium alloy has considerable advantages as the material of automobile engine bracket (compared with steel and aluminum alloy).
