Product Description

Introduction of Tungsten Alloy Balls (sphere)

  • Tungsten heavy alloys generally are refractory metal, which have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co, Mo, Cr, etc. It could be made as various shapes, such as rod, cube, block, brick, ring, etc.
  • Dimension: according to customer's requirement.
  • Density: 15.8-18.50 g/cm3
  • Composition: W content: 85-97%, W-Ni-Fe, W-Ni-Cu

Surface: Sinter state, Grind state, processing state with chamfer angle

 

The main performance of the tungsten alloy

  • Special Features:
  • High melting point
  • High ultimate tensile strength,
  • Extension of good
  • Low vapor pressure , heat resistant, good thermal stability
  • Easy processing, corrosion resistance, good shock resistance
  • High radiation absorption capacity , excellent impact resistance and crack resistance
  • Non-toxic environmental protection
Appliance of tungsten heavy alloy column:
  • Usually, tungsten alloy column could be manufactured as the parts of military defense, for penetrating projectiles, counterweights for military defense, projectiles in the missile weapons, armor piercing ammunition, and prefabricated fragments.

Balance weight: such as Pinewood Derby car counterweight, yacht counterweights, vehicle counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank counterweights, crankshaft counterweights etc.
