Introduction:
Cemented carbide balls, commonly known as tungsten steel balls, refer to balls and balls made of
cemented carbide. Cemented carbide balls can be ideally used in harsh environments, extremely
wear-resistant, impact-resistant, and corrosion-resistant ,Not easily deformed. Cemented carbide balls
are made of carbide (WC, TiC) micron powder of high hardness refractory metal, with cobalt (Co) or
nickel (Ni), molybdenum (Mo) as a binder, in a vacuum furnace or Powder metallurgy products sintered
in a hydrogen reduction furnace.
Product classification: It is mainly divided into tungsten-cobalt spheres (YG6, YG6X, YG8, YG10, YG13).
The number behind YG represents the cobalt content. For example: YG6 refers to 6% CO content, and
the remaining 94% WC, there is another type of tungsten nickel alloy balls (YN6, YN8, YN10, YN12), the
same number behind the same represents the nickel content. The specific gravity of the first two alloy
balls is 14.6-15.1, and there is also a type of alloy balls It is a titanium carbide ball with a low specific gravity.
Application:
Tungsten carbide ball was widely used in precision tools drawing and punching,high precision bearings,
high precision measuring instrument and appratus,water pump and brake pump,and various machinery
sealing accessories part in high-tech industry.
