Aluminum alloy
It is one of the light metal materials which is based on aluminum with some alloying elements added. In addition to the general characteristics of aluminum, aluminum alloy has some specific characteristics of alloy due to the different types and amounts of alloying elements. The density of aluminum alloy is 2.63 ~ 2.85g/cm3, has high strength (σb is 110 ~ 650MPa), the specific strength is close to high alloy steel, the specific stiffness is higher than steel, has good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, can be used as structural materials. It is widely used in aerospace, aviation, transportation, construction, electromechanical, lightweight and daily necessities.
Aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, non-toxic, easy recovery, excellent electrical conductivity, heat transfer and corrosion resistance, and is widely used in Marine industry, chemical industry, aerospace, metal packaging, transportation and other fields.

Aluminum alloy tube is a kind of seamless steel tube, aluminum alloy tube is divided into structural seamless tube and high pressure heat resistant aluminum alloy tube. Different from the production standard of aluminum alloy tube and its industry, aluminum alloy tube is annealed and tempered to change its mechanical properties. To achieve the required processing conditions. Its performance is higher than the general seamless steel tube variable utilization value, aluminum alloy tube chemical composition contains more Cr, high temperature resistance, low temperature resistance, corrosion resistance.

For aluminum alloy pipe commonly used epoxy, vinyl, phenolic resin, such as the construction process of anticorrosion coating, the general requirements are nearly white to aluminum alloy tube surface level, proved through practice, use the descaling grade removes almost all of the scale, rust and other dirt full meet the requirement of adhesion to coating and aluminum alloy tube, And the jet derusting process can be used to lower the cost of stable and reliable quality to achieve nearly white level conditions.
