What are the materials for automotive stamping parts
Author:
The materials for automotive stamping parts mainly include steel, aluminum alloy, stainless steel, copper, and magnesium alloy.
Steel
Steel is the most commonly used material for automotive stamping parts, accounting for 72% -88% of the vehicle's raw materials, mainly including low-carbon steel, high-strength steel, stainless steel, etc. Among them, conventional cold-rolled sheet metal has low cost, smooth surface, and is not easily deformed, making it suitable for structurally simple parts; High strength cold-rolled sheet has high strength but is prone to surface cracks; High performance hot-rolled sheet has high strength and corrosion resistance, but the cost is relatively high.
Aluminum alloy
Aluminum alloy has low density, light weight, and good corrosion resistance. It is commonly used in lightweight parts such as car doors and engine covers, which can reduce the weight of the entire vehicle and improve fuel efficiency. It has good formability and is not easily deformed, but its strength is slightly lower than that of steel.
Stainless steel and copper materials
Stainless steel has strong corrosion resistance and is commonly used for exterior parts and exhaust systems; Copper material is mainly used for components with high conductivity requirements.
Other materials
Magnesium alloy has high specific strength and rigidity, which can reduce vehicle weight, but it is costly and difficult to process, and its application is limited.
