Tungsten alloy block is the most common tungsten alloy product, its shape is square, rectangular or other shapes. The composition contains tungsten, nickel and iron. The main reasons why we choose tungsten alloy as the substitute of nickel, titanium and lead are as follows. The density of tungsten alloy is 16 ~ 18.5g/cm3, which is higher than that of nickel, titanium and lead. In addition, tungsten alloy also has good mechanical strength, low coefficient of thermal expansion and high elastic modulus.
Properties of tungsten alloy
Tungsten alloy is a kind of tungsten matrix alloy, the tungsten content is 85-99%. The density of tungsten alloy block is as high as 16.5-19.0g/cm3, which makes tungsten alloy the best raw material for counterweight. Tungsten alloy blocks can be used in racing cars, airplanes and sailboats. These have strict requirements for the volume of counterweight. In addition, tungsten alloy block has good corrosion resistance and machinability.
Application 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 counterweight, vehicle counterweight, aircraft counterweight, helicopter counterweight, marine counterweight and tank counterweight. The die is mainly used in the forming technology of material processing, including pressing the workpiece with die, so as to reduce the cross section and increase the length. Because of its high melting point and good corrosion resistance, tungsten alloy block becomes the best raw material for making mould.
Advantages of tungsten alloy
Why can tungsten alloy replace lead, aluminum and other materials for mold making? 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 nontoxic.
