According to the present development trend, future automotive research and development will give greater attention to the lightweight design of cars in order to safeguard the environment and conserve energy and resources. Lightweight automobiles can be produced by using lightweight materials including high-strength steel, aluminum alloys, magnesium alloys, and composite materials in the auto industry.
Advanced manufacturing techniques like hydroforming, laser tailor welding, and thermoforming are also possible. automobiles that are light. Due to their low density, strong corrosion resistance, and simplicity of production, aluminum alloys have been extensively used in lightweight automobiles.
Due to their lowest density, excellent die-casting formability, dimensional stability, and strong damping coefficient, magnesium alloys also provide unrivaled benefits in the lightweighting of automobiles.
