Automotive lightweighting has become the  global developing trend of automotive industry due to the increasingly strict requirements of environmental protection and energy conservation . Lightweight is an irreversible trend of automotive development, and increase the ratio of aluminium application is the most realistic option to realize lightweight design.

The superiority of increasing aluminium material in automotive is obvious weight loss efficiency, reducing energy consumption,  improving the car driving performance, as well as enhancing passenger's comfort and safety.
The aluminium material applied in automotive involves aluminium tube, profile and bars, presently domestic aluminum material applied in automobile industry focus on heat exchange system (air conditioning pipes, pipe joint and connector,expansion valve body,receiving dryer, water tank, evaporator, condenser, heater), chassis suspension system (shock absorber, ABS valve body, brake cylinder, control arm), auto air-condition compressor( high silicon alloy such as swash plate, plunger, fittings, ect.), guide rail, car window frame,  interior decoration parts, ect.
