Tape Wound Cores: 48 Alloy

What is 48 Alloy?

For more technical information please look at the official Magnetics Strip Wound Core Design Manual.

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.
