Compared with lead, high-gravity tungsten alloy is more suitable as counterweight for tennis, not only because it is non-toxic, healthy and relatively high density, but also because it has better corrosion resistance and oxidation resistance. So why do tennis rackets have counterweights?

One is to reduce the probability of twisting the racket. When the ball does not hit the center of the racket, the counterweight can effectively reduce the number of twists and reduce the torsion Angle of the racket, and then improve the accuracy and strength of the shot.

The second is to increase the effective hitting area of the racket face. Generally, the best hitting part of the racket is in the center or below the center of the line bed, but most players' hitting point is the upper part of the center of the line bed, which leads to weak hitting. Therefore, if the two and ten positions of the racket are weighted, it will improve the effective hitting area of the racket, so that even if the ball hits the upper part of the racket string bed, the hit can be more stable and more powerful.

The third is to increase the weight of the racket. If you just want to increase the weight of the racket to make the racket more powerful and stable when hitting the ball, you can add tungsten alloy pieces to the neck of the racket, or the position of six o 'clock, which will increase the swing weight of the racket, but also make the racket sacrifice some flexibility.

Due to its high density, non-toxic environmental protection and long service life, tungsten alloy stands out from many counterweight materials and is considered to be the best choice for racquet weight blocks.

In addition, tungsten alloy due to density, strength, hardness, ductility, electrical/thermal conductivity and other physical properties have significant characteristics, so in the defense industry, aerospace industry, medical industry, electrical industry and other industries have been widely used.
