Soft magnetic alloy allows more efficient designs

Specialty alloy producer, Carpenter Technology, has launched a soft magnetic alloy called CARTECH HYPOCORE. The alloy is said to exhibit excellent soft magnetic properties compared to existing commercialised grades of non-grain oriented electrical steel and is suited to applications within the aerospace, transportation, medical, energy, and consumer markets, among other sectors.

The CARTECH HYPOCORE alloy is claimed to address a previously unfilled performance need between CARTECH HIPERCO 50 alloy and commercial Silicon steels, with higher induction than Silicon steels but lower core losses than HIPERCO alloys. This new alloy exhibits low coercivity, high permeability, and high electrical resistivity, properties that allow motors and generators to be designed smaller and more efficiently.

“The movement towards high induction and low core loss electrical steels usable at high frequencies continues unabated due to the global shift toward electrification of transportation and distributed power generation,” said Dr Chins Chinnasamy, principal R&D metallurgist for magnetic alloys at Carpenter. “Our customers’ design priorities are to increase efficiency and reduce size, and that’s exactly what our product helps to accomplish.”
