carbide bearing ball,tungsten alloy bead
1. Name: tungsten carbide ball, cemented carbide ball, TC ball.
2. Material: tungsten carbide, cemented carbide, hard alloy, WC.
3. Diameter: 5.0mm. our tugnsten carbide ball diameter range from 0.5mm --50mm.
4. Grade: YG6, YG8. or as your request.
5. Made of virgin tungsten carbide raw material. this grinding
bearing carbide ball has very giid abrasice resistance.
6. After accurate grinding and polishing, the valve carbide ball
are of low frictional factor.
[Produce equipments about 5mm valve carbide ball]
Tungsten carbide balls are not solid tungsten carbide.
They are made of grains of tungsten and carbon held together in a
matrix of metal such as cobalt or nickel.
Under great heat and pressure the carbon atoms are actually packed
inside the tungsten atoms instead of
being joined side by side as with ordinary compounds.
Interstitial carbides, such as tungsten carbide (WC), form when
carbon combines with a metal that has an
intermediate electronegativity and a relatively large atomic
Making tungsten carbide is very difficult. First, you need to pack
the carbon atoms into the tungsten lattice.
Second, the tungsten is trying to grow into a single big crystal
but you want millions of small crystals.
These grains are combined with Cobalt powder and mixed in a ball
Tungsten carbide balls are mixed with grains allowed to run for
several days to get even
dispersal of the grains and the cobalt powder.
This powder is then dried and wax is added as a binder.
The wax holds the powder together and makes it somewhat slippery so
it presses into shapes well.
The shapes are pre-sintered in an atmosphere-controlled furnace at
temperatures of 1,000 - 1,500F.
The wax melts out and leaves the pieces sort of like a soft chalk.
These chalk pieces can be easily machined although they are also
easy to break and can be
chipped here if handled improperly.
