Title:
METHOD FOR PRODUCING FE-CO ALLOY ROD
Document Type and Number:
WIPO Patent Application WO/2024/048788
Kind Code:
A1
Abstract:
Provided is a method for producing an Fe-Co alloy rod whereby superior magnetic properties can be reliably obtained. This method for producing an Fe-Co alloy rod comprises a heating/straightening step in which tensile stress is applied while heating a hot rolled material of an Fe-Co alloy to a temperature of 500 to 900℃. The Fe-Co alloy comprising, by mass%: 95% or more of Fe + Co; 25 to 60% of Co; 1.70 to 2.10% of V; 0.01 to 0.15% of Mn; 0.008% or less of C; 0.01% or less of S; and inevitable impurities as the balance.
