Sintered alloy produced with HIP technique is a kind of high quality material, which features high density, segregation-free, micropore defect free. It stands out for its excellent anti-wear performance, making it a kind of desirable material for the twin screw extruder, especially for screw elements. Thus the severe contradiction between the hard screw surface and tenacious screw core is perfectly taken care of.
