Tungsten Heavy Alloy Properties

ASTM B777 (MIL-T-21014 / SAE-AMS-T-21014) is a standard specification for Tungsten Heavy Alloys (WHA). The specification is organized into four classes (1-4). Each categorization or classification represents a percentage amount of Tungsten (W) Alloy.

Class 1: W 90% 

Class 2: W 92.5% 

Class 3: W 95%

Class 4: W 97.5%

Tungsten Heavy Alloy Applications

There are many different ways to use Tungsten heavy alloy (WHA). Mostly, we provide WHA parts for ballast weights, radiation shields, boring bars, ordnance components, and other things that need to be really heavy and flexible.

WHA is commonly used in various applications, such as counterweights, inertial masses, radiation shielding, and ordnance products. It is preferred for its strength, density, and weight, making it suitable for applications that require balance weights, such as turbines, crankshafts, and helicopter rotors.

WHA is also used in commercial and military aircraft, spacecraft, defense vehicles, transportation systems, warheads, munitions, and fragmentation.

In the medical industry, WHAs are used for X-ray shielding in applications such as CT and imaging technologies, nuclear medicine shielding, and surgical robots. The alloying of tungsten allows for the production of complex shapes and forms needed for critical medical devices and technologies.

Below are the typical uses of WHA:

  • Aerospace: Counterweights, balance weights, vibration damping.
  • Defense: Armor-piercing rounds, vehicle counterweights, kinetic penetrators.
  • Oil & Gas: Drilling tools for enhanced hardness and resistance.
  • Industrial Machinery: Balance weights for improved stability and performance.
  • Manufacturing: Wear-resistant components for welding, machining, molds, and castings.
  • Nuclear: Radiation shielding, reactor components for safety and efficiency.
  • Medical: Radiation protection in diagnostic/therapeutic devices.
  • Electronics: Compact, high-density components for reliability and performance.
  • Automotive: Counterweights for vehicle balance and handling.
  • Sporting Equipment: High-density materials for sports gear, optimizing performance.
