Using tungsten carbide ball to replace the ordinary steel ball indenter for Brinell hardness measurement is required by international standards, so as to expand the Brinell hardness measurement range.
High-precision tungsten carbide balls are widely used in oil drilling and deep-sea drilling pump valve balls and ball seats, which are also one of the most critical components in oil pumps.
Compared to steel valve ball, tungsten carbide valve ball has several times longer service life, it can better adapt to harsh working conditions in the well, reduce leakage, improve pump efficiency, and extend pump inspection cycle.
Tungsten carbide valve balls have high hardness, wear resistance, corrosion resistance etc, mainly used in various sealing work, like: oil pump, thermal power plant water ash removal and slag discharge system, fluid sealing Spin the ball...
Non-magnetic tungsten carbide balls are of high hardness, good wear resistance, small thermal expansion coefficient and good chemical stability, making it has times of longer service life than that of non-magnetic steel balls.
Tungsten alloy materials have high specific gravity and small volume, have been widely used in vehicle counterweights with this requirement. The main shape of tungsten counterweight are tungsten balls, tungsten blocks or tungsten rods...
