[China Aluminum Industry Network] Aluminum profiles have been widely used by people in the modern era. There are many internal reasons for this. In the choice of materials, we are also faced with the choice, why choose aluminum materials instead of steel materials. With aluminum as the body material, some additional weight loss measures are also being considered. It is widely used in aluminum finishing processes in interior decoration, industrial and scientific fields. The strength of aluminum profiles is an important factor that must be considered when designing a product. When aluminum alloy components are used as components, the appropriate alloy should be selected according to the pressure applied. The aluminum alloy hubs on automobiles today actually contain other metals such as iron. Compared with ordinary aluminum alloy wheels, the ordinary wheels have good toughness and poor hardness. The aluminum alloy wheels have the opposite, but the hardness is good but the toughness is poor. Due to the material and process of manufacture, the stability of the iron hub at high speed is not good, the stability of the aluminum alloy wheel at high speed is very good, and the acceleration and heat dissipation aluminum alloy hub is also superior. Aluminum profile strength is an important factor that must be considered when designing a product. When an aluminum profile is an aluminum alloy component as a component, an appropriate alloy should be selected according to the pressure applied.
