Because the magnesium alloy material is all metal structure has the lowest density of metal, and accompanied by the gradual maturity of the die casting process, magnesium alloy application in consumer electronics products is more and more widely, the magnesium alloy become in titanium alloy and aluminum alloy in the highest price of the metal materials. Due to the application of magnesium alloy gradually mature, so people in different electronic products in the application, also put forward different requirements.
