Hymu80 (Permalloy80/Mumetal)high initial permeability alloy Plate, sheet, strip, wire, rod

Introduction

Hymu80 is 80% nickel with additions of  iron and molybdenum as main elements in turn this alloy offers an extremely  high initial permeability.

Characters

Hymu80 is only moderately resistant to  moisture and atmospheric corrosion; it used mainly in in transformer cores  but is well known for its magnetic properties which are used for shielding  electrical components from magnetic fields. "HYMU 80" has a minimum  DC permeability of 80,000 at a flux density of 40 gauss when heat treated by  the recommended procedure and test in accordance with ASTM 596.

Specific Gravity - 8.7g/cm

Curie Temperature - 830°F (410°C)

Applications

l    High performance magnetic cores such as toroids and  stacked laminations

l    Magnetic shielding to protect sensitive components from  extraneous magnetic fields

l    Magnetic sensors

l    Current sensors

l    Any application requiring high permeability magnetic  material, with a low coercive field and low losses, in the range from low  frequency up to 1MHz

l    Vacuum chamber vessels and liners
