The Potential Properties And Advantages Of Tungsten

Tungsten-nickel-iron alloy is a compound created on tungsten (about 90-98%) and added with iron, nickel, copper, or other constituents. The precise gravity is usually 17.0-18.5. Tungsten nickel-iron alloy is an essential tungsten-based substantial alloy. They are alloys comprised of nickel and iron added to tungsten and alloys, adding extra metal elements. The nickel-iron ratio usually encompasses 7: 3 or 1: 1.

Moreover, the tungsten ball has high hardness and dimensional stability. These characteristic makes tungsten balls a perfect option for precision high-load bearings, hydraulic valves, inertial navigation systems, linear bearings in slideways, ball screws, gauging and checking instruments, and meters. Tungsten carbide balls are also used to work-harden, ballizing, and improve fretting fatigue strength.

Here are some of its characteristics and benefits, and mechanical properties that help you understand this alloy’s importance.


Tungsten carbide balls are perfect for applications where risky hardness must be complemented by high resistance to wear and influence. They are well-suited to raised abrasion, corrosion, temperatures, humidity, and poor lubrication conditions. Also, their standard material is composed of 94% tungsten carbide and 6% cobalt binder.

Moreover, these tungsten alloy ball is minor in volume and high in specific gravity. Because of this, they are ideal for fields that need small parts with high precise gravity, such as fishing sinkers, golf weights, weights, armor-piercing projectiles, and missile warheads. Also, they are helpful for shotgun bullets, oil drilling platforms, and prefabricated fragments.

Also, Tungsten alloy balls are helpful in high-precision fields, such as flywheel weights, the balance of pendulum clocks and automatic watches, mobile phone vibrators, anti-vibration tool holders, etc. High specific gravity tungsten alloy balls are extensively beneficial in industrial and military fields as balance weights.
