What is the aluminum alloy wheel hub mold? What is the material of aluminum alloy wheel hub?

It is an aluminum alloy die casting mold or an extrusion casting mold. Using squeeze casting instead of pressure casting to produce aluminum alloy wheels not only overcomes the defects of easy formation of air holes and oxide inclusions in die castings, but also improves the yield and material utilization.

Chemical composition (mass fraction) of wheel material is: 1.5% ~ 3.5% Cu, 10.5% ~ 12.0% Si, < 0.3% Mg, < 1.0% Zn, < 0.5. Mechanical performance requirements: σ b > 276 MPa, σ s > 1 15 MPa, σ > 4.4%, HB > 92.
