China Heavy Density Tungsten Plate for Counter Weight

Tungsten Alloy Block

Tungsten alloy block is the product with regular shape, such as square, rectangle and other
shape. Composition of it also includes Nickel, Titanium and Lead. The reason that we choose
tungsten alloy to be substitution of Ni, Ti, and Al are follows. It's have excellent electric and
thermal conductivity with high density of 16 g/cm3 to 18.5g/cm3, which is much higher than
Nickel, Titanium and lead. Tungsten alloy also have good mechanical strength and small
coefficient of expansion and high elastic modulus.
Tungsten alloy is a kind of W-based matrix with the W content of 85-99%. Its density can be
up to 16.5-19.0g/cm3, which makes the product to be the ideal raw material as counterweight.
Tungsten alloy block can be used in racing cars, airplanes and sailboats where size plays an
important role. Besides, it has excellent corrosion resistance and machinability.
Due to the above mentioned advantage of tungsten alloy, it can be manufactured as the parts
of military defense, extrusion die, some counterweights, such as yacht counterweights, vehicle
counterweights, airplane counterweights, helicopter counterweights, boat counterweights, tank
counterweights, etc.
Extrusion die is one of the forming techniques used in material processing, consisting of
forcing the work pieces through a die, thereby reducing its cross section and increasing its length.
Tungsten alloy block is the popular material for extrusion die because of its high melting point and
corrosion resistance.
