The main components of 90WMoNiFe alloy include tungsten (W), molybdenum (Mo), nickel (Ni) and iron (Fe). The proportions of these elements are not fixed but are adjusted according to the specific use and desired properties of the alloy. Generally speaking, the content of tungsten is between 40% and 70%, the content of nickel is between 20% and 30%, the content of iron is between 5% and 15%, and the content of molybdenum is based on the proportion of other elements Make appropriate adjustments.
The proportion of each element has a significant impact on the properties of 90WMoNiFe alloy. First, as a matrix element, tungsten’s high melting point, high hardness and excellent corrosion resistance provide the alloy with good physical and chemical properties. The tungsten content directly determines the hardness and wear resistance of the alloy. Alloys with high tungsten content usually have higher hardness and better wear resistance.
Secondly, the addition of molybdenum can further improve the strength, toughness and thermal stability of the alloy. The presence of molybdenum helps reduce the thermal expansion coefficient of the alloy, allowing it to maintain stable performance in high-temperature environments. At the same time, molybdenum can also improve the hardenability of the alloy and prevent temper brittleness, thus enhancing its overall performance.
Nickel plays a role in improving the plasticity and workability of the alloy, while also improving the corrosion resistance of the alloy. The appropriate addition of nickel can make the alloy have good toughness and ductility while maintaining hardness.
Iron is used as an auxiliary element in the alloy to adjust the cost and performance of the alloy. The right amount of iron content can reduce production costs while maintaining alloy properties.
To sum up, the proportion of each element in 90WMoNiFe alloy needs to be precisely controlled according to specific needs to obtain alloy materials with optimal properties. By adjusting the content of each element, the alloy’s properties such as hardness, toughness, wear resistance, corrosion resistance and high temperature stability can be optimized to meet application needs in different fields.
