Product Description

                                                   Tungsten Alloy Ball

  Tungsten alloy ball is small in volume but very dense, which means the product can be used
in various fields requiring small but heavy parts, such as the counterweights for golf club, fishing
weights, counterweights for military applications, projectiles in the missile weapons, armor
piercing ammunition, hunting pellets, prefabricated fragments, the missile weapons, armor
piercing ammunition; counterweights for oil logging; also some fields concerning with precision
industry, such as mobile phone vibrator, clock cube, self-winding watches, anti-vibration toll
holders, flywheel weights, etc. Heavy tungsten alloy balls or tungsten weight is widely used in
weight or balance industrial, and in military.
  Tungsten alloy ball is widely used in ball valve and bearing. We can offer various grades and
sizes of tungsten alloy balls. And the stringent requirements of each procedure to ensure that the
products produced comply strictly with your request. We adopt the advanced techniques and
depend on the highest quality materials. Our product has the high durability and wears resistance,
which can improve the service life of the bearing, while elevating the value of your products.
  Tungsten alloy ball is used as the hunting shot for shotguns. A shotgun is a firearm that is
usually using pellet filled shells instead of using bullets. The shot pellets from a shotgun spread
upon leaving the barrel, and the power of the burning charge is divided among the pellets, which
means that the energy of any one ball of shot is fairly low. In a hunting context, it makes shotguns
useful primarily for hunting birds and other small games.
  High density, great hardness and resistance to high temperature make tungsten to be one of
the most sought -after material for shotgun pellets in hunting history. Density of tungsten alloy
shot is about 18g/cm3, which is comparable only to gold, platinum, or bismuth. To understand
how the density factors of tungsten heavy alloy into performance, let us look at two spheres about
the same size of tungsten alloy shot, a golf ball and a ping -pong ball. The golf ball is far denserand will fly farther and hit harder. Now shrink the ball size down to two single points, we can get
clear comparison graphic. Tungsten alloy will fly farther, hit harder and penetrate deeper. Another
unique property of tungsten alloy is that it is non-toxic and environmentally friendly. Therefore, it
is safe for people to handle and work. It is our leading products; Chentian Company can provide
tungsten alloy shot as your requirements.
