product details

PermalloyNi79Mo4 Magnetic Alloy

Introduction
Permalloy magnetic alloy is of Fi-Ni alloy with a wide nickel content range of35%-90%. The biggest characteristic of permalloy is high magnetic permeabilityof weak magnetic field. And its saturation induction density is generallywithin 0.6-1.0T.
