Electric resistance element and raw material for the same and method for preparing the same |
摘要 |
The material for an electrical resistivity element contains at least 20 mass % and at most 60 mass % of nickel, less than 5 mass % of iron and the remaining part including unavoidable impurities and cobalt. The material for the electrical resistivity element is manufactured by preparing a composition that contains at least 20 mass % and at most 60 mass % of nickel, less than 5 mass % of iron and the remaining part including cobalt, melting and casting the composition to obtain an ingot, removing the surface of the ingot by hot working, and performing cold-working and heat treatment on the hot-worked body.
