Abstract

PURPOSE: To provide abrasion-resisting permalloy, by combining fixed proportions Ni-Fe alloy, metallic elements having energy smaller than the standard carbide forming free energy, and carbon.
CONSTITUTION: Ni-Fe alloy is added with one or more elements that form a carbide more easily than iron, that is, elements having the standard carbide forming free energy smaller than ΔG°, the standard carbide forming free energy of iron, for example, Zr, Ti, Mn, together with carbon. From consideration of the magnetic characteristics and processing of magnetic materials, the following composition is used: Ni 55W85 weight %, the total amount of elements that form a carbide more easily than iron 0.5W10 weight %, carbon 0.01W0.3 weight %, and iron for the remainder. By this, it is possible to increase abrasion resistance without impairing magnetic characteristics and processing facility.
