[0002] As we all know, magnesium alloy plate is a steel plate material made of magnesium alloy, which has low density, excellent strength and corrosion resistance. Magnesium alloy plate has good formability and strength and is suitable for hot stamping in hot stamping equipment. Hot stamping is a metal forming process performed at high temperature. It can heat the metal material to make it softer and easier to plastically deform, thereby realizing the forming of complex shapes.
