Tungsten Alloy Balls For Balance Weight
Tungsten alloy balls are also called tungsten heavy alloys because they weigh more than twice as much as iron or steel. High specific gravity tungsten alloys are usually refractory metals with two-phase complexes consisting of W-Ni-Fe, W-Ni-Cu or even W-Ni-Cu-Fe. Some tungsten alloys add rare earths and/or other metals such as Co, Mo and Cr. Tungsten heavy alloys have very high melting points, are twice as dense as steel and more than 50% heavier than lead.

The tungsten alloys are mainly divided into two series: W-Ni-Fe and W-Ni-Cu, and even W-Ni-Fe-Cu. In contrast, W-Ni-Fe alloy has better mechanical properties and plays a great role in various fields of defense industry and national economy. It is a very important new military material in national defense industry and has been gradually popularized in various civil industries.
Tungsten heavy alloy has a series of excellent characteristics, significant ratio: general ratio of 16.5-18.75g/cm3, high strength: tensile strength of 700-1000mpa, strong ray absorption capacity: its ability is 30-40% higher than lead, large thermal conductivity: 5 times that of die steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity; Good weldability and machinability.
Tungsten alloy balla are small in size and can be used for the balance force of missile weapons, projectiles, armor piercing shells, hunting gear, shotguns, prefabricated fragments, missile weapons, ammunition and armor piercing shells; Balance force of oil logging; There are also some precision instrument fields, such as mobile phone vibrator, clock counterweight, watch counterweight, mobile phone vibrator, flywheel counterweight, tungsten ball, etc High specific gravity tungsten balls and tungsten counterweights are widely used in counterweights and factories, as well as in military.
