China High Density Tungsten Ball for Bearing

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/cm3Composition: 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 goodLow vapor pressure , heat resistant, good thermal stabilityEasy processing, corrosion resistance, good shock resistanceHigh radiation absorption capacity , excellent impact resistance and crack resistanceNon-toxic environmental protectionAppliance 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.
