The main components of tungsten-molybdenum-nickel-iron alloy include tungsten (W), molybdenum (Mo), nickel (Ni) and iron (Fe). Among them, tungsten is the main matrix element, accounting for the highest proportion, usually above 90%. The content of molybdenum is relatively small, usually around 4%. The content of nickel and iron may also vary, but generally maintain a certain ratio, such as 7:3 or 1:1. Tungsten-molybdenum-nickel-iron alloy mainly refers to 90WMoNiFe alloy, and the main element ratio is: W90, Mo4, Ni4, Fe2; therefore, conventional tungsten-molybdenum-nickel-iron alloy also becomes 90WMoNiFe alloy.
The specific contents of these elements may be adjusted according to different alloy grades and production processes to meet different application requirements. The composition of tungsten-molybdenum-nickel-iron alloy is designed to achieve optimal physical and mechanical properties such as density, hardness, strength, thermal conductivity, thermal expansion coefficient, etc.
It’s important to note that specific ingredients may vary depending on producer and customer needs. Therefore, when selecting and using tungsten-molybdenum-nickel-iron alloy, its composition needs to be determined based on actual application scenarios and requirements.
