How to choose suitable for their own aluminum alloy material, the choice of alloy brand is a key step,Each alloy brand has its own corresponding chemical composition, the added trace elements determine the mechanical properties of aluminum alloy conductivity corrosion resistance and so on.

     Each aluminum alloy brand can find its corresponding chemical composition in GB / T3190-2020.Line 1 has high soft conductivity elongation,2 series has high hardness good welding performance,3 series has good anti-corrosion performance, good elongation,4 series with low melting point is mainly used for welding,5 series alloy distribution ratio gap is relatively large,6 series strength is hard, cost-effective, the market consumption is more in the hard alloy,7 series of high hardness welding performance is general, so commonly used high strength parts,At present, the market applications of the 8 series mainly focus on aluminum foil products.
