High-density Tungsten Alloy Ball For Counter WeightTungsten Alloy Ball are also called tungsten heavy alloys because
their weight is more than twice that of steel. High specific
gravity tungsten alloy is usually a refractory metal containing
W-Ni-Fe, W-Ni-Cu or even W-Ni-Cu-fe two-phase complex. Some
tungsten alloys have rare earths and/or other metals such as Co,
Mo, and cr added. Heavy tungsten alloy has a very high melting
point, twice the density of steel and more than 50% heavier than
lead. Tungsten Alloy Ball SPECIFICATIONS COMPOSITION | Chemical Composition | 90%W | 93%W | 95%W | 97%W | | State | Sinter | Vacuum | Forge | Sinter | Vacuum | Forge | Sinter | Vacuum | Sinter | Vacuum | Density

Tungsten Alloy Ball Picture:
Introduction and characteristics of Tungsten Alloy Ball- Tungsten alloys are mainly divided into two series: W-Ni-Fe and
W-Ni-Cu, and even W-Ni-Fe-cu. In contrast, the W-Ni-Fe alloy has
better mechanical properties and plays a huge role in the defense
industry and various fields of the national economy. It is a very
important new type of military material in the national defense
industry and has been gradually popularized in various civilian
industries.
- Tungsten heavy alloy has a series of excellent properties,
significant ratio: generally 16.5-18.75g/cm3, high strength:
tensile strength 700-1000mpa, strong ray absorption capacity:
30-40% higher than lead, thermal conductivity: mold steel 5 times;
low thermal expansion coefficient: only 1/2-1/3 of carbon steel,
good electrical conductivity; good welding and machining.
Application of Tungsten Alloy Ball- Tungsten alloy is small in size and can be used in missile weapons,
shooting, armor-piercing projectiles, hunting tools, shotguns,
prefabricated fragments, missile weapons, ammunition and armored
balances, oil measuring balances and precision instruments, such as
mobile phone vibrators, clock weights, watches Weights, cell phone
vibrators, flywheel weights, tungsten balls, etc. High specific
gravity tungsten balls and tungsten counterweights are widely used
in counterweights, factories and military fields.
