1. Aluminum alloy has low density, but high strength, close to or exceeds high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry and its usage is only second. Yu Steel.
2.Some aluminum alloys can be heat treated to achieve good mechanical properties, physical properties and corrosion resistance. Heat treatment strengthening. It is characterized by high hardness but poor plasticity. However, it has poor corrosion resistance, high temperature softening, excellent thermoplasticity and is suitable for forging, so it is also called forged aluminum alloy.
3.Stainless steel is mainly nickel-chromium alloy, which is corrosion-resistant. When there is anti-corrosion requirements for the products produced, stainless steel will definitely be used. Secondly, the stainless steel surface can be processed as needed, and the appearance is beautiful and smoother than the aluminum alloy.
4.However, the cost of stainless steel is higher than that of aluminum alloy. Nowadays, stainless steel is basically used by high-end customers or government public works. In short, it is beautiful and not easy to rust and not easy to damage.
