Material properties and advantages
1.Lightweight and high specific strength
The density of aluminum alloy is only 1/3 of that of steel, but through alloy design and heat treatment, its specific strength can reach 3-4 times that of steel, significantly reducing the weight of the vehicle body.
2.Corrosion resistance Multi-layer composite aluminum plate reduces copper diffusion and inhibits galvanic corrosion through sandwich design, and is suitable for parts such as heat exchangers that are exposed to complex environments for a long time3.
3.Processability and surface quality 60 series aluminum alloy has excellent formability, but traditional processes are prone to tensile strain marks. Optimizing heat treatment can improve surface uniformity and reduce stamping defects.
