R60 - high temperature tungsten steel Density: 12.8g/cm3 Hardness: 83HRA bending strength: 3200N/mm2 uses: hot extrusion of aluminum alloy by a large copper hard refractory metal compounds and bonding metal by powder metallurgy process made of an alloy material. Carbide with high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature also remained unchanged , at 1000 ℃ still very high hardness. Carbide is widely used as a tool material, such as turning, milling, planer, drill, boring knives for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to machine materials.
