Product Detail


Introduction of 4Y32 Aluminum alloy plate block
4Y32 Aluminum alloy plate block belongs to the AI-Si series of wrought aluminum alloy. Si is the main alloying element. Since Si has a smaller specific gravity and linear expansion coefficient than aluminum, it is also a face-centered cubic crystal and has a large latent heat of fusion. It can be added to the aluminum matrix to increase the alloy’s Fluidity, reduce the shrinkage and thermal cracking tendency of the alloy, reduce porosity, shrinkage cavities and improve air tightness. After effective modification and heat treatment, the product has excellent mechanical properties. Physical properties and corrosion resistance. The Si element in the 4Y32 Aluminum alloy plate block is as high as 10% ~ 12%, and it is combined with Cu, Mn. Mg. Sb and other elements to make there are more eutectic crystals and primary Si eutectic phases in the structure. The brittleness and hardness of the alloy have improved the wear resistance, which has attracted more and more attention from the aviation, aerospace and transportation sectors.
