Permalloy Alloys

Permalloy (Ni-Fe) is the generic term for a nickel-iron magnetic alloy with about 20% iron (Fe) and 80% nickel (Ni) content (although other formulations are available. It has a very high magnetic permeability, low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. These properties are critical for its industrial applications, allowing it to be used in thin films where variable stresses would otherwise cause large variations in magnetic properties.

Superalloy (Ni-Fe-Mo) is an alloy composed of Ni (75%), Fe (20%), and Mo (5%) and is a magnetically soft material with extremely high magnetic permeability and low coercivity.
Typical Applications

Permalloy is used in magnetic recording heads, the production of inductors and electrical transformers.

This superalloy is used in manufacturing components for radio engineering, telephony, and telemechanics instruments.

Packaging Options

Jars, pails, drums, multi-ply paper bags, bulk bags, and fiberboard containers
