Tungsten carbide ball/TC alloy ball High precision tungsten carbide balls /Tungsten alloy ball Tungsten Carbide ball is mainly composed of high-hardness refractory metal carbide (WC, TiC) micron powder with cobalt (Co) or nickel (Ni), molybdenum (Mo) as binder in vacuum furnace or Sintered powder metallurgy products in hydrogen reduction furnace.
Nowadays common cemented carbides have YG, YN serials.

The available grades and sizes are shown in the below table.
| Grade | Composite | HRA(Hardness) | Density(g/cm³) | T.R.S(MPa) | Description |
| YG6 | 6% Co | 91 | 14.6-15.0 | 1600 | The highest wear resistance make this an excellent general purpose grade for use in pumps and valve |
| YG8 | 8% Co | 89 | 14.4-14.8 | 1800 | With better shock resistance than YG6, This grade is typically used as a mining grade where thoughness and abrasion resistance are also important .it has also proven useful in bearing applications |
| YG6X | 6% Co | 92 | 14.6-15 | 1850 | Sub-micro alloy, high hardness and wear resistance than YG6, little lower toughness than YG8, Used in parts where high wear resistance and high toughness are required. |
| YG13 | 13% Co | 90.5 | 14.1-14.5 | 1950 | high toughness and hardness grade. |
| YN6 | 6% Ni | 90 | 14.5-14.9 | 1450 | The highest hardness and wear resistance and corrosion resistance. Used in parts where corrosive condition in high temperature are required. |
| YN8 | 8% Ni | 88 | 14.4-14.8 | 1650 | With higher hardness and wear resistance. Used in parts where shock resistance and corrosion are required. |
| YN9 | 9% Ni | 88 | 14.4-14.8 | 1900 | With higher hardness and wear resistance. Used in parts where shock resistance and corrosion are required. |
| YN12 | 12% Ni | 86 | 14.0-14.4 | 1800 | Higher toughness for impact load. Used in parts where better shcok and impact are required. |
