Product structure and advantages of tungsten copper alloy
From the perspective of product structure, tungsten copper alloy is a binary or multi-component alloy with tungsten and copper as the main components, usually prepared by powder metallurgy. Among them, tungsten copper alloy W70-Cu30 is the most common one, with a density of 13.5g/cm3, a hardness of HRC30-35, and a melting point of 1470-1490℃. In addition, according to different uses, tungsten copper alloy can also add other elements such as iron and nickel to improve its performance.
The main advantages of tungsten copper alloy are its high density, high hardness, high melting point, high elastic modulus and excellent corrosion resistance. In addition, tungsten copper alloy also has good fatigue resistance and low expansion coefficient, and can be widely used in various high-strength, high-wear-resistant, high-precision and high-reliability application scenarios.
