Tennis rackets counterweights refers to installing the counterweights in the edge of the tennis rackets so as to achieve the aim of altering the balance of tennis rackets to improve the hitting force of the players. The tennis rackets counterweights are mainly made of tungsten alloy materials, which are non-toxic and environmentally friendly. The counterweights that made of tungsten alloy (the following picture shows the different shapes of tungsten alloy counterweights) can be divided into ordinary tungsten alloy counterweights and special tungsten alloy counterweights in accordance with the uses of counterweights.

As the name suggests, ordinary tungsten alloy counterweights means that can be prepared by rough machining, it is no strict to the counterweights’ surface and accuracy requirements. The weight and volume of this kind tungsten alloy counterweights are relatively large, and mainly used as the counterweight blocks such as: marine ballast counterweights.

 

Comparing with the ordinary tungsten alloy counterweights, Special tungsten alloy counterweights relatively has the finer manufacturing process,the shapes of counterweights are more complex, and their weights and volumes are relatively small. Special tungsten alloy counterweights are mainly used to the things which need to weight, such as golf head counterweights, watches counterweights, the crankshaft counterweights of autos, the fly wheels counterweights of heavy machines and tennis rackets counterweights and so on. Why should we increase the counterweights to tennis rackets? What’s the theory of controlling the tennis rackets with counterweights? And which materials can be used to prepare tennis rackets counterweights?
