Which is better, aluminum alloy shell or stainless steel shell. The excellent characteristics of aluminum and its alloys are good appearance, light weight, good machinability, good physical and mechanical properties, and good corrosion resistance, which make aluminum and its alloys considered as the most economical and practical materials in many application fields. The density of aluminum is only 2.7g/cm3, about 1/3 of that of steel, copper and brass (7.83g/cm3 and 8.93g/cm3 respectively). Aluminum has excellent corrosion resistance under most environmental conditions, including air, water (or salt water), petrochemical products and many chemical systems.

     The surface of aluminum is highly reflective. Radiated energy, visible light, radiant heat and electric waves can be effectively reflected by aluminum, while anodized and dark anodized surfaces can be reflected or absorbed. Polished aluminum has excellent reflectivity in a wide wavelength range, so it can be used for various decorative applications and applications with reflective functions.

     Aluminum usually has excellent conductivity and thermal conductivity, and some special aluminum alloys with high resistivity have also been developed. These alloys can be used, for example, in high torque motors. Aluminum is often used because of its good conductivity. On the basis of the same weight, the conductivity of aluminum is almost twice that of copper. The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is conducive to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.

     Aluminum is non-ferromagnetic, which is an important attribute of the electrical and electronic industry. Aluminum is not spontaneous combustion, which is very important for handling or contacting flammable and explosive materials. Aluminum is non-toxic and is often used in food and beverage containers. Its natural surface state has a pleasant appearance. It is soft and shiny, and can be colored or dyed with textured patterns for beauty.

     Which is better, aluminum alloy housing or stainless steel housing? I believe you have understood that some aluminum alloys have higher strength than structural steel, but pure aluminum and some aluminum alloys have extremely low strength and hardness. In modern life, aluminum has been widely used in various industries.
