Tungsten alloy counterweights are mainly used for balancing weights, such as tire counterweights, ship counterweights, hoist counterweights, and so on. Tungsten alloy counterweights are made of tungsten-nickel-copper alloy and tungsten-nickel-iron alloy. Although both are a typical three-phase alloy in tungsten-based alloys, due to the different binders used, the two have different physical and chemical properties, There are also big differences in process parameters and uses.
Generally, the powder is pressed into an embryo body after the raw material ratio, and then plastically processed by sintering, and finally the required tungsten alloy counterweight is obtained. Such tungsten alloy weights have high melting point, high density, high tensile strength, good toughness, good wear resistance, excellent ductility, low thermal expansion coefficient, strong oxidation resistance, and good electrical and thermal conductivity.
Of course, the metal powder materials of the raw materials are different, and the final products obtained are also different. Different material ratios will also lead to changes in the multi-attributes of the finished product. For example, if the color changes and too much copper is added, the color of the tungsten alloy tungsten alloy weight will tend to be copper-colored. Due to the good thermal conductivity of copper, the thermal conductivity of the finished tungsten alloy weight will also become better. If Reduce the binder phase material and increase the tungsten content, the melting point and density of the tungsten alloy weight will be higher.
