Centrifugal Casting alloy powder

Due to the development of fiber-reinforced plastics, inorganic fillers are increasingly used in making halogen-free plastics. Making such plastics demands superior properties to resist wear and corrosion on the extruder components, especially, extruder screws and barrels. As a result, bi-metallic barrels are increasingly used. To satisfy both the demanding requirements on the properties of the interior barrel surface and the centrifugal casting process, the company has developed a series of powders to meet the challenge. These powders are iron, nickel, cobalt base alloys as well as Ni+WC. We are the only domestic supplier of gas-atomized powders for centrifugal casting. Their low melting points, low oxygen and impurities result in porosity-free, fine-grained structures with superior wear and corrosion resistance.
