The main purpose of using automotive lightweight materials is to reduce the weight of the car body, which has a dual effect on reducing engine power consumption and reducing total vehicle weight. To this end, we should first find a breakthrough in the body manufacturing materials. There are several ways to do this:
1. Use lightweight materials with low density and high strength, such as aluminum-magnesium light alloy, plastic polymer materials, ceramic materials, etc.
2. Use high-strength steel with the same density, the same elastic modulus and good process performance and thin section thickness.
3. Use lightweight structural materials based on new material processing technology, such as continuous extrusion variable section profiles, metal matrix composite panels, laser welded sheets, etc.
