Abstract:Aluminium is the most widely distributed metal elements in the earth, and has been the most universal engineering and construction materials for its excellent combined properties. China has a large aluminium deposition, and has become large country for production and consumption of aluminium and metal proccessed products, whose quality approach to those in developed countries. Up to now, all the countries are endvored to decrease pollution and energy consumption, improve working rates and maintenance of equipment, low-mass materials are always the main choice. Aluminium and its alloys will then be more widely used. The main developing trends for aluminium alloys are ligh strength high tonghness, high corrosion resistance, high temperature resistance and high modulous Al alloys, and also Al-base composites and synthesized materials. The research frontier lays in significantly improving ductility, toughness and combined properties as well as strength, and processing techniques innovation is the most important.
