Research status and prospects of non-heat treated aluminum alloys
Aluminum alloys have advantages such as low density,good castability,high specific strength and good corrosion resistance,and are mainly used in the automotive industry and aerospace fields.In recent years,with the rapid development of the new energy vehicle industry,non-heat treated(NHT)aluminum alloys have become a new type of material for preparing lightweight,high-strength and low-cost structural components due to their ability to form complex components through integrated die casting without the need for subsequent heat treatment processes.This article summarizes the research status of non-heat treated aluminum alloys,mainly introducing new materials,die casting processes and mechanical properties of non-heat treated aluminum alloys based on Al-Si and Al-Mg series.It also looks forward to the development trend of non-heat treated aluminum alloys.
