Application of aluminum alloy in automotive structural parts - extrusion aluminum

As the aluminum alloy extruded profile can simply produce a variety of complex section structure of steel can not be produced as one of the effective means of automotive lightweight has attracted much attention.

Extruded profiles are widely used as structural materials in various parts of automobiles due to their light weight and good rigidity.

In 1990, Japanese automobile manufacturers applied all kinds of extruded materials to cars in the world, producing the NSX sports car with an all-aluminum body, among which extruded materials accounted for 12% of the total amount of materials.With the development of aluminum processing technology, high-precision 3d bending processing technology of profiles, the establishment of microstructure control and uniform yield strength control heat treatment technology of 6xxx series alloy materials, the application space of extruded profiles in automobiles has been greatly expanded.

INSIGHT, a hybrid car developed by Honda of Japan in the late 1990s, has increased the amount of extruded profiles from 12 per cent of NSX to 30 per cent.At the same time, the car body with aluminum alloy frame is much better than steel body in both weight reduction and rigidity.
