Supermalloy

From Wikipedia, the free encyclopedia

Supermalloy is an alloy composed of Ni (79%), Mo (5%), and Fe.

It is a magnetically soft material. The resistivity of the alloy is 6 nΩ·cm²/cm. It has a high magnetic permeability and a low coercivity. Supermalloy is used in manufacturing of components of radio engineering, telephony, and telemechanics instruments.
