Application of Cast Aluminum Alloy in Lightweight of Automobile Chassis Structural Parts
Based on the lightweight development of new energy vehicle chassis components,the application status and development trend of aluminum alloy casting technology in its lightweight at home and abroad are summarized.The research shows that:at present,the low pressure casting and vacuum integrated die casting are mainly used,and the extrusion casting replaces part of steel,iron and forged aluminum parts,and the integrated die casting is developed.For the large die-casting parts with reinforced hollow structure,it is difficult to achieve the balance of high core strength and good collapsibility at present,low pressure casting is still used,and the mechanical properties are improved by heat treatment.
