The Purpose Of The Aluminum

The strength of pure aluminum is small and can be increased after work hardening, but the plasticity is seriously decreased. If the aluminum alloy is prepared by adding appropriate amount of other elements in aluminum, it has the characteristics of high strength, good plasticity, and high specific strength. It can be comparable with high-quality alloy steel and become an excellent lightweight structural material, known as "flying metal". Aluminum accounts for more than 50% of aircraft structure. With aluminum alloy instead OF some steel components, the weight OF the motor vehicle can be reduced by 20%-75%, the fuel consumption can be reduced by 8%, and the life of the mechanical parts can be extended by 15%. In the electrical industry, aluminum is more economical and widely used to make conductive materials such as cables and wires than copper. Aluminum is used in the chemical industry as conduits for liquefied natural gas, refrigerators and petroleum refiners. Aluminum for vehicle and ship construction industry is developing rapidly. Aluminum is also widely used in the construction industry. Aluminum is a good packaging material, reducing agent, deoxidizer, aluminum - calcium alloy with superplasticity can be made of special-shaped appliances and various crafts.
