Processing of Tungsten Heavy Alloy

  1. The tungsten powder is mixed with other metals, pressed, and sintered to achieve the desired shape. Liquid phase processing involves melting the matrix alloy to dissolve tungsten, forming a microstructure with large tungsten grains (20-60µm) dispersed in the matrix.
  2. Cutting with tungsten steel or superhard tools is suitable for precision machining.
  3. Electrospark machining uses electric pulse discharge to process the workpiece.

Tungsten Heavy Alloy Applications

Tungsten heavy alloy products come in various shapes such as rods, cylinders, bars, blocks, plates, tips, strips, sheets, spheres, pellets, balls, discs, rings, and tubes. They are used in diverse fields due to their unique properties like high density, yield strength, hardness, and elongation.

Applications span industries globally:

  • Sports: golf clubs, fishing weights, darts, yachts, and racing cars.
  • Medical: radiation shielding, source holders, collimators, isotope containers, and nuclear syringes.
  • Scientific: heat sinks, oil drilling, and mining equipment.
  • Military: used as a substitute for depleted uranium in certain military applications.
  • Decorative: gold-plated tungsten bars, bricks, paperweights, coins.
  • High-temperature environments: rocket igniters, turbines.
  • Environmental: fishing sinkers, jigs, and weights, as a lead alternative.

Tungsten heavy alloy's popularity stems from its unique properties and versatile applications across various sectors.
