PURPOSE: To enhance the temp. sensitivity by adding Co, Ni and one or more among P, B, C and Si so as to provide a prescribed composition. n CONSTITUTION: The titled alloy has a composition represented by a formula (Co 1-a Ni a ) 100-z X z (where X is one or more among P, B, C and Si, (a) is 0.2W 0.8 and (z) is 15W20). In the composition ≤5 atomic% Cr may be substituted for the Co. The alloy undergoes a large change in the magnetic permeability due to temp. close to the Curie point, and the temp. range of the change is narrow, so the permeability is changed sharply. The setting temp. is changed to ≤200°C. n COPYRIGHT: (C)1982,JPO&Japio |
