Carbide is an alloy material made of powder metallurgy hard alloy and cemented metal powder metallurgy process.
Carbide with a high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance, even at temperatures of 500 ℃ also remained unchanged , Still have very high hardness at 1000 ℃.
Carbide is widely used as cutting tool materials, such as turning tools, milling cutters, planing knives, drill bits, boring tools, 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 materials.
Alloy Features:
1. High hardness (86 ~ 93HRA, equivalent to 69 ~ 81HRC);
2. Good heat-hard (up to 900 ~ 1000 ℃, maintain 60HRC);
Good wear resistance.
Carbide cutting tools than high-speed steel cutting speed 4 to 7 times higher tool life 5 to 80 times. Manufacturing molds, measuring tools, life-span alloy tool steel 20 to 150 times higher. Can be about 50HRC cutting hard materials.
However, carbide brittle, can not be cut, it is difficult to make a complex shape of the overall tool, which often made of different shapes of the blade, the use of welding, bonding, mechanical clamping and other methods installed in the body or mold body .
