4Y32 aluminum alloy extruded bar for aviation&aerospace

4Y32 aluminum alloy extruded bar belongs to Al-Si wrought aluminum alloy product, which
has the advantages of large thermal expansion coefficient, high strength and good corrosion
resistance at high temperature. The Si element in 4Y32 aluminum alloy is as high as 10% 12%,
combined with Cu, Mn, Mg, Sb and other elements to produce plenty of eutectics, primary
siand strengthened phases in the structure.With the characteristic of hard-brittle, the wear resistance of the alloy is improved. Therefore 4Y32 aluminum alloy extruded bar is increasingly
valued by the aviation,,aerospace and transportation sectors.Thetypical use of rotating slip rings
used under high temperature and wear conditions.
