Permalloy materials
Characteristics
•YMPC is the PC type permalloy.
•YMPC has a low coercive force though it possesses the highest permeability.
•YMPC is the optimum material for magentic head because of high wear resistance and less deterioration after resin molding.
•We can provide special specs for the use by bare material or without molding.
•Referential standards: JIS C2531
