Carbide ball has a very wide range of application areas, such as ball, navigation systems, precision parts stamping and stretching, precision bearings, instruments, meters, pen, spraying machine, water pump, mechanical parts, seal valve, brake pump, punching, oil field, laboratory hydrochloride, hardness measuring instrument, the high-quality fishing gear, weight, finish machining and other industries!
1:High strength, high wear resistance, high precision, high temperature resistant, corrosion resistant.
2:They are mainly used for the sealing of valves of oil pumps in petroleum industry's sand containing wells, viscous oil wells, sea oil wells and high pressure sulfur resistant oil wells, etc.
3 They are used with compatible cemented carbide valve seats. The surface finish, tolerance class and tolerances of dimensions have respectively reached the standards of the machine industry: G5, G10, G16, G40 and G100 of JB/T 9145-1999.
4:Precision machined cemented carbide balls of other grades and specifications are also available based on customers' demands.
5:Compatible high precision valve seats can also be made available.
YG6 YG8 tungsten carbide ball for valve pair & oil industry
Product Description
| Product name | Tungsten carbide balls |
| Series | YG6 YG6x YG8 YN6 YN9 |
| Feature | Large hard Tungsten Carbide ball has high hardness, wear resistance, corrosion resistance, bending resistance, and bad use environment, and can replace all steel ball products. Carbide ball hardness ≥ 90.5, density = 14.9g/cm3. |
| Density | 14.9g/cm3 |
| Product process line | The production process of cemented carbide ball is similar to that of other cemented carbide products, mainly including powder preparation → recipe according to application → wet grinding → mixing → crushing → drying → sieving → adding molding agent → drying → sieving Prepared mix → granulation → cold isostatic pressing → forming → sintering → forming (blank) →grinding → packaging → storage. According to the specific application requirements and related parameters, there are carbide alloy ball, tungsten steel ball, tungsten ball, high-density alloy ball and other carbide ball products. The smallest carbide ball can do about 0.3 in diameter. |
