Do you know the performance of cemented carbide?
High hardness (86-93HRA, equivalent to 69-81HRC);
Good thermal hardness (can reach 900-1000℃, maintain 60HRC);
Good wear resistance.
The cutting speed of carbide tools is 4 to 7 times higher than that of high-speed steel, and the tool life is 5 to 80 times longer. For manufacturing molds and measuring tools, the life is 20 to 150 times longer than that of alloy tool steel. It can cut hard materials of about 50HRC.
However, cemented carbide is very brittle and cannot be cut. It is difficult to make it into a complex integral tool. Therefore, it is often made into blades of different shapes and installed on the tool body or mold body by welding, bonding, mechanical clamping, etc.
An alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, its high hardness and wear resistance remain basically unchanged even at a temperature of 500°C, and it still has a high hardness at 1000°C.
Cemented carbide is widely used as tool material, such as turning tools, milling cutters, planers, drills, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. It can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult-to-process materials. Now the cutting speed of new cemented carbide tools is hundreds of times that of carbon steel.
