WNiFe Machined Heavy Tungsten Alloy Spheres For Counterweight Heavy Tungsten Alloy Spheres are also called tungsten
alloys because they weigh more than twice the weight of
steel.High-specific gravity tungsten alloys are usually refractory
metals containing W-Ni-Fe, W-Ni-Cu, and even W-Ni-Cu-Fe
complexes.Some tungsten alloys are added with rare earths and / or
other metals, such as Co, Mo, and Cr.Heavy tungsten alloys have a
very high melting point, twice as dense as steel, and are more than
50% heavier than lead. Heavy Tungsten Alloy Spheres SPECIFICATION | Chemical Composition | 90%W | 93%W | 95%W | 97%W | | State | Sinter | Vacuum | Forge | Sinter | Vacuum | Forge | Sinter | Vacuum | Sinter | Vacuum | Density

Heavy Tungsten Alloy Spheres Picture:
Introduction and characteristics of Tungsten Alloy Spheres- Heavy tungsten balls are mainly divided into two main series:
W-Ni-Fe and W-Ni-Cu, and even W-Ni-Fe-Cu.In contrast, W-Ni-Fe
alloys have better mechanical properties and play a huge role in
various fields of the defense industry and the national economy.It
is a very important new type of military material in the national
defense industry, and is gradually popularized in various civil
industries.
- Tungsten alloy has a series of excellent properties, significant
ratio: general 16.5-18.75g/cm3, high strength: tensile strength
700-1000mpa, strong ray absorption capacity: 30-40% higher than
lead, high thermal conductivity: 5 mold steel; low thermal
expansion coefficient: only 1 / 2-1 / 3 of steel, good
conductivity; good welding and machined.
Application of Heavy Tungsten Alloy Spheres - The tungsten ball is small and used in missile weapons, projectile,
armor piercing, hunting equipment, shotguns, prefabricated
fragments, missile weapons, armor piercing and balance bombs; some
precision instruments such as mobile vibrator, clock weights, watch
weights, mobile vibrator, flywheel weights, tungsten ball and
tungsten weight, widely used in counterweight, factory and army.
