High-density tungsten alloys offer a unique combination of density, mechanical strength, processability, corrosion resistance, and economy. These multifunctional materials offer clear advantages over traditional high-density materials such as lead or uranium. Incredible strength, consistent durability and lasting value – our tungsten heavy alloys are ideal for radiation shielding, counterweights and counterweights, boring bars and grinding sleeves, crankshaft balances, rotating inertia members, ordnance components, and high-temperature Perfect choice for tool applications.

W-Ni-Fe alloy and W-Ni-Cu alloy (tungsten content 90%~97%) are conventional high-density tungsten alloys. Characteristics of tungsten high alloys (W-Ni-Cu alloy and W-Ni-Fe alloy):

  • High density (17-18.5g/cm3)
  • High melting point
  • Abrasion resistance
  • High tensile strength
  • Good extension ability
  • Low vapor pressure
  • Excellent thermal stability and
  • High radiation absorption capacity

Due to these advantages, they are widely used in various fields such as sports, industry and medicine.

We offer a variety of high-density alloys including rods, plates, sheets, foils, and rods. We also have extensive machining capabilities, allowing us to offer standard sized weights or custom products completed to your required specifications.

Basic parts: tungsten alloy plates, tungsten alloy rods, customized parts (according to drawings)

Counterweight: tungsten ejector rod, tungsten counterweight, tungsten armor piercer, tungsten boring bar

Shielding: tungsten radiation shielding, tungsten syringe shielding, tungsten collimator, isotope container
