CEMENTED Carbide's hardness refers to the ability to resist other hard objects to cause depression deformation. The hardness of the ordinary Cemented Carbide is 86-93HRA (equivalent to 69-81HRC). Because it is high (far higher than ordinary metals), it is difficult to make complicated shapes. Factors affecting the hardness of CEMENTED Carbide include chemical composition, raw material ratio, production process and process parameters.

According to the different chemical composition, CEMENTED Carbide can be divided into tungsten cobalt (YG) CEMENTED Carbide, tungsten titanium cobalt (YT) CEMENTED Carbide, and tungsten titanium cobalt (YW) CEMENTED Carbide, etc. as follows:

The hardness of YG3X CEMENTED Carbide is not less than 92HRA, which is suitable for cast -iron, non -ferrous metals and alloy quenching steel alloy steel small cutting surfaces.

The hardness of YG6 CEMENTED Carbide is not low 89HRA, which is suitable for machining the semi -semi -sperm of the medium cutting speed of cast iron, non -metallic metal and alloy non -metallic materials.

The hardness of YG6A CEMENTED Carbide is not less than 91.5HRA, which is suitable for hard cast iron, semi -precision processing of non -ferrous metals and alloy, and semi -precision processing and processing of high manganese steel, quenching steel, alloy steel.

The hardness of YG6X CEMENTED Carbide is not less than 91HRA, which is suitable for fine processing of ordinary cast iron.

YG6X-1 CEMENTED Carbide's hardness is not less than 90HRA, suitable for cast iron, non-metallic metal and its alloy non-metallic materials, the semi-essence, thick car threads, semi-essence milling and semi-essence milling and semi-sperm milling and semi-sperm mills during intermittent cutting. Square milling, thick expansion and extension of holes.
