Aluminum matrix composites have low density, high specific strength and modulus, and good thermal fatigue resistance, but their application in automobiles is restricted by price and production quality control.

The main specifications of automobile models are continuously optimized. On the premise of retaining the main parameters of specifications, the structural strength of the whole vehicle is improved and the consumption of consumables is reduced.

The use of aluminum alloy parts on the car can effectively reduce the vehicle weight, so that the center of gravity of the car is reduced, the real realization of the vehicle lightweight.
