Application
Tungsten alloy balls are tungsten alloy products used for counterweights or lethal components, and are known as the smallest high-density balls in the field of tungsten alloys. This means that they can be applied in many fields, such as small and high-density areas such as golf clubs, fishing counterweights, military defense balance, etc.
Tungsten alloy balls have a small volume and can be used for the balance force of missile weapon pellets, armor piercing shells, hunting equipment, shotguns, prefabricated fragments, missile weapons, and ammunition armor piercing shells; Balance force of oil logging; There are also some precision instrument fields, such as mobile phone vibrators, clock counterweights, watch counterweights, mobile phone oscillators, flywheel counterweights, tungsten balls, etc. High density tungsten balls and tungsten counterweights are widely used in counterweights and factories, as well as in military applications.
