Aluminum alloy is one of the most widely used nonferrous metal structural materials in the industry.With the rapid development of industrial economy, the demand for welding structural parts of aluminum alloy is increasing day by day.At present, aluminum alloy is the most widely used alloy.Aluminum alloy density is low, but the strength is higher, close to or exceed the quality of steel, plastic good, can be processed into a variety of profiles, with excellent conductivity, thermal conductivity and corrosion resistance, the industry is widely used, the amount of usage is next to steel.Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.Hard aluminum alloy belongs to AI - Cu - Mg series, generally contains a small amount of Mn, heat treatment can be strengthened. It is characterized by high hardness but poor plasticity.Super duralumin belongs to Al - Cu - Mg - Zn series, which can be strengthened by heat treatment. It is the aluminum alloy with the highest strength at room temperature, but poor corrosion resistance and fast softening at high temperature.Forging aluminum alloy is mainly al-zn-mg-si series alloy, although the addition of more kinds of elements, but less content, so it has excellent thermoplastic, suitable for forging, so it is also called forging aluminum alloy.The downstream application of aluminum alloy industry is very broad, the production pattern of different fields, the market competition and the current situation of the industry are quite different.If main production hardware, lamps and lanterns, toys and so on the use of ordinary aluminum alloy parts, this kind of manufacturer homogenization competition is serious, often face fierce price competition, enterprise benefit is generally poor.The production of automotive aluminum alloy parts in the automotive production and sales decline in the context of the general trend of growth, high-end sectors such as aviation, rail transit, high-speed rail car market has maintained sustained rapid growth.The industry is also gradually entering the period of industrial structure adjustment. High-end production capacity is gradually increasing, while low-end production capacity is gradually eliminated. The growth of industrial production capacity shows obvious cyclical fluctuations.
