China Permalloy E11c Ni79Mo4 79HM Soft Magnetic Alloy Wire Manufacture and Factory

Permalloy E11c Ni79Mo4 79HM Soft Magnetic Alloy Wire

Short Description:

Permalloy 80 is an alloy of nickel, iron and molybdenum. It is a soft magnetic alloy with exceptionally high magnetic permeability. The alloy has a low coercivity, near zero magnetostriction, and significant anisotropic magnetoresistance. The low magnetostriction is critical for industrial applications,

where variable stresses in thin films would otherwise cause a ruinously large variation in magnetic properties.

Model NO.: Permalloy

Resistivity: 0.55

Elongation (≥ %): 15-25

Grade: E11C

Ni : 78.5-80.0%

Feature: High Initial Permeability
