Tungsten alloy block (tungsten nickel iron, tungsten nickel copper)
Tungsten alloy block is the most common tungsten alloy product, and its shape is square, rectangular or other shapes. The composition contains tungsten, nickel and iron. The main reasons why we choose tungsten alloy as a substitute for nickel, titanium and lead are as follows. Tungsten alloy has good electrical and thermal conductivity, with a density of 16~18.5g/cm3, which is higher than nickel, titanium, and lead. In addition, tungsten alloy also has good mechanical strength, low thermal expansion coefficient and high elastic modulus.
Properties of tungsten alloy block
Tungsten alloy is a tungsten matrix alloy with a tungsten content of 85-99%. The density of tungsten alloy block is as high as 16.5-19.0g/cm3, making tungsten alloy the best raw material for counterweights. Tungsten alloy blocks can be used for racing cars, airplanes and sailing boats. These have strict requirements on the volume of the counterweight. In addition, the tungsten alloy block has good corrosion resistance and machinability.

Use of tungsten alloy block
Tungsten alloy has the above advantages, so tungsten alloy can be made into weapon parts, molds and counterweights, such as speedboat counterweights, vehicle counterweights, aircraft counterweights, helicopter counterweights, ship counterweights and tanks Counterweights, etc.
The mold is mainly used for forming technology in material processing, including pressing the workpiece with a mold to reduce the cross section and increase the length. Due to its high melting point and good corrosion resistance, the tungsten alloy block becomes the best raw material for making molds.
Advantages of tungsten alloy block
Why can tungsten alloy be used to make molds instead of other materials such as lead and aluminum? The reason is that the melting point of 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.
