Aluminum alloy has low density, but relatively high strength, close to or surpassing high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, and its usage is second only to steel .
Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance. Heat treatment can be strengthened. It is characterized by high hardness, but poor plasticity. However, it has poor corrosion resistance, rapid softening at high temperature, excellent thermoplasticity, and is suitable for forging, so it is also called forged aluminum alloy.
Stainless steel is mainly a nickel-chromium alloy, which is corrosion-resistant. When there is a requirement for corrosion resistance of what is produced, stainless steel will definitely be used. Secondly, the surface of stainless steel can be processed as needed, and its appearance is more beautiful and smoother than that of aluminum alloy.
However, the cost of stainless steel is higher than that of aluminum alloy. Now there is no shortage of money or stainless steel is basically used in government public works. In short, it is beautiful, not easy to rust, and not easy to damage.
