48 Alloy

For Special Transformers & Transducers

48 Alloy, a 50% nickel-iron alloy, has a round B-H loop and exhibits lower saturation flux density, squareness, coercive force, and core gain than the Orthonol types. It is useful in devices requiring lower coercive force such as special transformers, saturable reactors, and proportioning magnetic amplifiers. AC core losses are typically lower than with Orthonol.

48 Alloy is a replacement for VAC discontinued PERMAX M®
