Abstract
A material having a high magnetic permeability made by a basic composition consisting of 75-82 weight percent of nickel, 2-6 weight percent of molybdenum, 1 or less weight percent of manganese, 1 or less weight percent of silicon and the remainder iron, and by an additive consisting of at least two different types of elements, one of which types of elements being an element selected from a first group of elements consisting of zirconium, vanadium, tantalum, chromium and tungsten, and the other being at least one element selected from a second group of elements consisting of titanium, zirconium, vanadium, niobium, tantalum, chromium and tungsten but different from said an element of the first group, said additive being contained in said material in an amount within the range of 1-8 weight percent. This material exhibits a high mechanical strength, and a high resistance to wear due to friction and a high magnetic permeability.
