Tungsten alloy weights have a long history of development. China has entered the heyday of bronze castings between 1700 and 1000 BC, and the process has reached a fairly high level. Europe also began producing counterweights around the eighth century.
For example, in the 15th and 17th centuries, Germany, France and other countries have laid a number of cast iron pipes that supply drinking water to residents. After the industrial revolution of the 18th century, industries such as steam engines, textile machines and railways rose, and castings entered a new era of service for large industries. In the 20th century, the development of weights was very fast, and tungsten alloy weights were discovered and applied at this time. One of the important factors is the advancement of product technology, which requires various mechanical and physical properties of castings to be better. Has good machinability.
Advantages of tungsten alloy weights in tennis rackets
1. High specific gravity: Adding tungsten alloy weight to the tennis racket can ensure the stability of the tennis racket during use and provide the controllability of the tennis racket.
2. High tensile strength and hardness: Due to the high tensile strength and hardness of tungsten alloys, it can be used in limited spaces such as tennis rackets.
3. Easy to process: Because the tungsten alloy is easy to process, this gives the designer a large space to design, and can meet the needs of the design according to the characteristics of the tennis racket.
Tungsten alloy counterweights are non-toxic and environmentally friendly, replacing toxic and environmentally hazardous products. They are harder than steel, high density, and tungsten is 30% ahead of similar products. At the same time, they are lighter than the traditional ones, creating twice the weight of lead and retaining their shape for a long time. These features also make tungsten alloy weights more advantageous than other materials in making tennis rackets.
