The hardness of tungsten-molybdenum-nickel-iron alloys varies depending on factors such as specific alloy composition, processing conditions, and testing methods. Generally speaking, tungsten-molybdenum-nickel-iron alloy has high hardness, usually reaching a Rockwell hardness (HRC) of more than 50, or even around 60 HRC. In some cases, the Rockwell hardness of the alloy may range from HRB 70 to HRC 30.
In addition, Vickers hardness (HV) usually ranges from 200 to 400. However, these hardness values are general ranges, and specific values may vary depending on the alloy’s specific composition, heat treatment process and testing methods. If a precise hardness value is required, it is recommended to consult the material data sheet of the alloy or conduct actual testing to obtain accurate data.
