90WMoNiFe alloy is an alloy composed of tungsten as the matrix and a small amount of nickel, iron, molybdenum and other alloying elements, which is produced by powder metallurgy. This type of alloy has a low expansion coefficient, high thermal conductivity and good red hardness, so it is widely used in the field of die-casting molds and anvils in the field of hot forging valves.
As for the specific types of 90WMoNiFe alloy bars, one of the main grades I know is 90WMoNiFe, whose element composition is W90, Mo4, Ni4 and Fe2. This alloy is mainly used in the field of die-casting. In addition, there are alloy materials such as 90WMoNiFe/93WNiFe, which can be used as hot riveting bearing materials because of their excellent comprehensive high-temperature performance.
