Product Description

Tungsten Alloy Special Shape Products

  Due to high density but small volume, high melting point, excellent hardness, superior
wearing resistance, high ultimate tensile strength, high ductility, well machinability, non-toxic and
environmental friendly, high impact resistance and crack resistance, tungsten counterweights
become more and more popular for each fields.
  Tennis player strikes the ball and seeks to achieve as much control as possible with the
greatest force applied to the ball. This occurs when the ball is struck at a position on the strings
known as the "sweet spot" which is the central area of the strings. No two players have identical
swings and therefore two different players may swing slightly different with the same racket.
Further, since the tennis racket weight and overall structure is fixed after it is made. The only way
to achieve a different arrangement is to obtain a new racket with different weight or weight
distribution. It would, however, be advantageous if weights could be easily added at selected
points of the racket that would improve a players overall swing. Selected weighting could be used
to not only increase the head weight for more powerful serve, but also to correct imbalances in a
player's swing. Tungsten counterweight is the most favorable material in it.
 Tungsten ski balance weights relate to the technological sector of skis and the associated
accessories which allows optimum performance to be achieved in all the sporting disciplines of
downhill skiing. More particularly, the product relates to an assembly consisting of ski, ski-boot
and associated bindings in which one or more weights of variable size are mounted on the ski in
order to achieve better balancing of the ski itself and a reduction in the vibrations of its various
parts caused by the fact that the pressure stresses acting on the zone of bearing contact of the ski with the snow change continually and very rapidly as regards the intensity and the point of
application.
  Application of tungsten alloy counterweight
1.Counterpart for machinery, ships, aircraft
Balance weight, flyweight used in machinery; weight rod used in oil well logging industries;
anti-shock cutter rod; vibrator used in game machine; ballast counterweight parts used in
navigation, sailing etc.; gyroscope used in aerospace, airplane counterweight and so on.
2.Counterweight used in sports.Counterweigh used in racing car, rowing; various specifications and requirement counterweight in golf head etc.
3.Special requirement of counterweight. Any place need counterweight but with small space can choose tungsten heavy alloy counterweight as it is the ideal material. We can conduct design,
manufacture, and process as per requirement of customer no matter standard or special
products.
