High density cemented carbide tungsten carbide bearing ball
Introduction: Carbide ball is made by refractory metal carbides (WC, TiC) micron powder as the main component, cobalt (Co) or nickel (Ni), molybdenum (Mo) as a binder, sintered in a vacuum furnace or hydrogen reduction furnace.
1.For sealing of valves of oil pumps in petroleum industry's sand containing wells, viscous oil wells, sea oil wells, high-pressure sulfur resistant oil wells, compatible Cemented Carbide valve seats, etc.
2.Various grades for cemented carbide balls/pellets can be supplied
according to the customer's drawings.
3.The surface finish, tolerance class, and tolerances of dimensions
have respectively reached the standards of the machine industry.
Application:
Tungsten carbide ball was widely used in precision tools drawing
and punching, high precision bearings, high precision measuring
instrument and apparatus, water pump and the brake pump, and
various machinery sealing accessories part in the high-tech
industry.
Diameter:
Dia. 2, 5, 7, 8, 10, 12mm (or 5/8, 3/4, 15/16, 1-1/8, 1-1/4, 1-3/8, 1-1/16, 2-1/4") and more.
| Grade | Density (g/cm3) | Typical Value | Application Scope | |
| Hardness | Bending Strength | |||
| YG3 | 15.10~15.30 | 92.5 | 1700 | Superior wear resistance only less than YG3X, sensitive to impact and vibration, suitable for cast non-ferrous metal and its alloy finish turning, semi-finish turning, thread finish turning, and hole expanding. |
| YG3X | 15.10~15.30 | 93.6 | 1450 | Best wear resistance in Tungsten and Cobalt alloy, but not good in anti-impact property, suitable for cast iron, non-ferrous and alloy, quenched steel, alloy steel small cutting section machining at high speed. |
| YG6X | 14.80~15.00 | 92.4 | 2000 | Belong to small granule Tungsten carbide alloy, wear resistance higher than YG6. Suitable for machining cold and hard alloy cast iron and heat resistant alloy steel, as well as finish machining for normal cast iron. |
| YG6 | 14.80~15.00 | 91.1 | 2100 | High wear resistance but less than YG3, better anti-impact and anti-vibration than YG3X, Suitable for cast iron, non-ferrous and alloy, non-metal material semi-finish machining and finish machining. |
| YG6A | 14.8~15.00 | 92.8 | 1850 | Belong to small granule alloy, wear resistance high, suitable for semi-finish machining of cold and hard cast iron, non-ferrous and alloy, as well as semi-finish machining and finish machining for quenched steel, alloy steel |
| YG8 | 14.6~14.80 | 90.5 | 2300 | High bending strength resistance, better anti-impact, and anti-vibration than YG6, suitable for cast iron, non-ferrous and alloy, non-metal material rough machining at low speed. |
| YG522 | 14.20~14.40 | 92.5 | 2000 | High wear resistance, and high strength, the special grade for bamboo and wood processing, also suitable for non-ferrous and non-metal material cutting process. |
| YG546 | 14.55~14.75 | 90.5 | 2700 | High flexibility and high strength, withstand high impact load, suitable for stainless steel and cast iron rough processing |
| YG610 | 14.60~14.80 | 93.5 | 2000 | High wear resistance and high hardness, suitable for cast iron, high-temperature alloy, quenched material cutting continuous and discontinuously. |

| YG643 | 13.60~13.80 | 93.3 | 1700 | High wear resistance, high anti-stick property, suitable for cast iron, high temperature cast iron, high-temperature alloy, stainless steel, quenched steel, and non-ferrous processing. |
| YG813 | 14.30~14.50 | 92 | 2200 | Good wear resistance, high bending strength resistance, and anti-stick property, suitable for processing high-temperature alloy, stainless steel and high Manganese steel and other material. |
Production and test of Carbide Balls:
1)Carbide Balls will start to prepare the powder as per the customer’s requirement
with our wet-grinding machine
2) Before mass production, we need to do a trial pressing and sintering, and we check the
appearances and the sizes of the samples with a micrometer to
ensure that the requirements of the drawings can be met before
batch production
3) Bulk production, press the raw materials to shape blanks,
and carbide tips must be passed by semi-finished inspection.
4) sinter blanks to finish (HIP) and finished products inspection
to ensure the best quality and production capacity.
