ELKONITES TC5, TC10, TC20, and TC53 tungsten carbide-copper alloys are press-sinter-infiltrated materials with a refractory content ranging from 50 to 70 wt.%. They are strong materials with high properties. They also have good resistance to arc erosion and contact welding. These materials are generally used in oil devices to protect the contact from oxidation. This datasheet provides information on composition, physical properties, hardness, and bend strength. It also includes information on high temperature performance as well as joining and powder metal forms.Filing Code: W-26. Producer or source: CMW Inc.
