What is aluminum extruded enclosure case material?
Aluminium alloy profile is the most widely used in industry of non-ferrous metal structural materials, in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, construction, decoration and have been extensively applied in chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welding structural parts is increasing day by day, so that the research on the weldability of aluminum alloy is also deepening.
Aluminum alloy is widely used to promote the development of aluminum alloy welding technology, at the same time, the development of welding technology and expand the application field of aluminum alloy, thus the welding technology of aluminum alloy is becoming one of the hot spot of research.
The density of pure aluminum (rho = 2.7 g/cm3), is about 1/3 of the iron, low melting point (660 ℃), aluminum is face-centered cubic structure, therefore, has the very high plasticity (delta: 32 ~ 40%, and bits of: 70 ~ 90%), easy to machining, can be made into all kinds of shapes, plates, corrosion resistant performance is good. However, the strength of pure aluminum is very low, and its annealing temperature is about 8kgf/mm2, so it is not suitable for structural materials. Through long-term production practice and scientific experiments, people gradually strengthen aluminum by adding alloy elements and applying heat treatment, and a series of aluminum alloys are obtained. The alloy formed by adding a certain element can maintain the advantages of pure aluminum, such as light weight, but also have a higher intensity, the jing b value can reach 24~60kgf/mm2 respectively. So that its "strength" (the ratio of intensity and the proportion of sigma b/rho) is better than a lot of alloy steel, become the ideal structural material, widely used in machinery manufacturing, transportation, machinery and aviation industry, the aircraft fuselage, skin, such as compressor with aluminum alloy manufacture, in order to reduce weight. The structure weight can be reduced by more than 50% by using aluminum alloy instead of steel plate.
