Tungsten Nickel Copper Tungsten Alloy Block Low Thermal Expansion Coefficient

high density tungsten nickel copper W-Ni-Cu alloy block counterweight

Tungsten alloy block (tungsten nickel copper)

tungsten alloy block is the most common tungsten alloy product, its shape is square,rectangular or other shape. composition containing tungsten nickel and copper. main reasons we choose tungsten alloy as a substitute for nickel, titanium and lead  are as follows :Tungsten alloy has good electrical conductivity and thermal conductivity, the density 16 to 18.5 g/cm3 is higher than nickel titanium lead .In addition, tungsten alloy has good mechanical strength, low thermal expansion coefficient and high elastic modulus.

The properties of tungsten alloy block

Tungsten alloy is a kind of tungsten matrix alloy, the tungsten content is 85-99%.tungsten alloy block is as high as 16.5 to 19.0 g/cm3 density, making tungsten alloy is one of the best raw materials of counterweight .Tungsten alloy block can be used in the car, the plane and sailing .These have strict requirements on a volume of balancing .The other tungsten alloy block and good corrosion resistance and machinability.

Tungsten alloy block application

Tungsten alloy possesses the advantages of the above, so the tungsten alloy can be made into weapons parts, molds and counterweight parts, such as yacht counterweight parts, vehicle weight, the weight, the helicopter counterweight parts, Marine counterweight and tanks counterweight parts, etc Mold is mainly used for the forming technology of material processing, including with mold pressed workpiece, so as to reduce the transverse section and increase the length Due to the high melting point and good corrosion resistance, makes tungsten alloy block production mold of the best raw materials

Advantages of tungsten blocks

Why is tungsten alloy used in molds instead of other materials such as lead and aluminum?
The reason is that the melting point of a tungsten alloy is more than 10 times that of lead, which is very important for mold processing. In addition, the hardness of tungsten alloy is very high. Another important reason is that tungsten alloy is environmentally friendly and non-toxic.
