Zhuzhou Jinggong Cemented Carbide Co., Ltd. Is one large specialist maker and the leading supplier of tungsten carbide tips and inserts.


Tungsten Carbide ball is made by a refractory metal WC and a cemented metal Co or Ni for bonding together, and then molding, and high temperature for sintering to a ball. The company's production of cemented carbide ball is in all of the original raw materials. Production of ball has the following advantages: Small porosity, high hardness, anti-acid and anti-alkali corrosion, specifications between 2.5mm and 76.2MM. The Grades are tungsten-cobalt alloy ball YG6, YG6X, YG8, YG10, YG15, tungsten nickel alloy ball YN6, YN8. It Is widely used in a variety of hard alloy plant in high-precision alloy ball, grinding, abrasive, chemical, oil, etc

At the same time, we also offer the high accuracy multi-level specifications alloy balls from the range of G10 to G500. The products are widely used in the hardness measuring instrument, auto parts, precision instruments and other hardware supporting products.

The component of YG6(tungsten carbide ball):
Applications: YG6 carbide ball is widely used in a variety of hardware industry, valves, bearings, die-casting, punching parts, grinding, measuring.
Features: The main components are tungsten-cobalt alloy (WC-CO) with a high hardness, HRA90-92, abrasion resistance is better, its wear resistance is hundreds time previous to steel balls

The component of YG6X(tungsten carbide ball):
Applications: YG6X carbide ball is widely used in a variety of hardware industry, valves, bearings, die-casting, punching parts, grinding, measuring, chemical, petroleum, and military.
Features: The main components are tungsten-cobalt alloy (WC-CO) with a high hardness it is a fine-grained alloy. It's hardness and wear resistance is a little better than YG6X alloy balls, but it's toughness is slightly lower than the ball of YG8, so it is suitable for production of wear-resistant alloy and Impact-resistant parts

The component of YG8(tungsten carbide ball):
Applications: YG8 carbide is widely used in ball valves, bearings, die-casting, punching parts, grinding, measuring, hardness tester, petroleum, chemical, aviation and aerospace.
Features: The main components are tungsten-cobalt alloy (WC-CO) with a high hardness and wear resistance, it's toughness is better than YG6 alloy ball and has good anti-vibration shock engaged in the performance, suitable for production of strong shock and vibration components
