Tungsten alloy valve ball has advantages of high hardness, good abrasion resistance, anti-corrosion, and adaptable to tough working environment. It is widely used in oil drilling, deep-sea drilling pump valve ball, ball seat, which is also one of the most critical components of the pump.
Tungsten alloy valve ball is made possible by P/M techniques. This is a technique where tungsten powder is mixed with nickel, iron or copper powder. It is then compacted and liquid phase sintered. The result is a very high-density machinable material having a homogeneous structure with no grain direction. This provides a material with unique physical properties and applications.
