What are the characteristics of 5754 O aluminum sheet for for auto body?
Lightweight: 5754 aluminum alloy plate has low density and is lighter than steel, which can reduce the weight of the vehicle body and improve fuel economy.
Strong corrosion resistance: the surface of the 5754 aluminum alloy plate is covered with a protective oxide film, which has good corrosion resistance and can be used in harsh environments.
Good formability: 5754 aluminum alloy sheet can be processed into complex body structures by forging, rolling, stretching and other processes.
High strength: 5754 aluminum alloy plate has high strength and can provide good body rigidity and stability.
Easy welding and processing: 5754 aluminum alloy plate has good weldability and machinability, and can be processed by conventional welding and processing techniques.
What is the specific purpose of 5754 O aluminum sheet for auto body?
5754 O-temper aluminum alloy plate for auto body is usually used in the manufacture of automobile shell, door, roof, hood, trunk lid and other parts, as well as important parts such as automobile chassis and floor.
Its high strength and corrosion resistance can ensure that the body will not deform or corrode for a long time; at the same time, its lightweight characteristics can also reduce the weight of the vehicle, improve the fuel economy of the vehicle and reduce carbon dioxide emissions.
