With the continuous development and improvement of processing technology, stainless steel and aluminum alloy casings will be more and more used in various fields. So do you know the difference between the aluminum alloy casing and the stainless steel casing?

Structure: The density of aluminum profiles is extremely small, the thermal conductivity is high, and the ductility is very good. Various aluminum profile alloys are made by synthesizing other metal elements, such as hard aluminum alloys, super hard aluminum alloys, anti-rust aluminum alloys, and cast aluminum alloys. In industry, aluminum profiles can be used to manufacture various heat exchangers, heat dissipation materials and cooking utensils, and can be made into aluminum alloy foil with a thickness of less than 0.01mm at 100°C~150°C.
Stainless steel is made of steel. During the smelting process, metals such as chromium, nickel, manganese, silicon, and copper are added. Chromium is the main alloying element. Generally, the content of chromium in stainless steel is at least 10.5%, while that of aluminum alloy is generally between 2.5×10³ kg/m³—2.8×10³ kg/m³, so the weight of the aluminum alloy casing is higher than that of the stainless steel casing. much lighter.
Corrosion resistance: The corrosion resistance of aluminum alloy is due to the addition of a corrosion-resistant oxide film on the surface, which can prevent further corrosion of the internal metal. Stainless steel is mainly nickel-chromium alloy, which is corrosion-resistant. Stainless steel is recommended if there is a need for corrosion resistance on the product being produced. The surface of stainless steel can be expanded and processed, and the appearance is cuter and smoother than aluminum alloy. But the cost of stainless steel is higher than that of aluminum alloy.
