The Nickel alloy718 sleeve is a forged product, and its internal structure reaches perfect performance through multiple extrusion deformations. During the continuous copper extrusion continuous production process, the extruded product is extruded from the Nickel alloy718 die cavity, and its temperature continues to increase. The product has not been deformed. The Nickel alloy718 of LANZHU SUPER ALLOY can meet the requirements of so many difficulties and protect the smoothness and deformation of the surface of the extruded product in continuous production.
