What are the advantages and disadvantages of aluminum alloy car bodies?
1 Answers
Advantages and disadvantages of aluminum alloy car bodies are: 1. The advantages of aluminum alloy include light weight, strong oxidation resistance, and high plasticity. It can be cold-formed and processed, and slightly deformed frames can be easily restored to their original shape. 2. Aluminum alloy car bodies are more expensive. Compared to steel car bodies, aluminum alloy bodies are more brittle and difficult to repair through sheet metal and painting after collisions, resulting in very high maintenance costs. 3. Due to low hardness and poor wear resistance, parts are more prone to wear and tear. It is not suitable for frequently moving parts. 4. The excessive plasticity of aluminum alloy means it cannot provide better protection for occupants in the event of an accident.
