Hymu80 (Mumetal)(Permalloy80) Soft Magnetic Alloy High Initial Permeability
Introduction of Hymu80
Hymu80 is 80% nickel with additions of iron and molybdenum as main elements in turn this alloy offers an extremely high initial permeability.
Characters of Mumetal
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 of Permalloy80
  • High performance magnetic cores such as toroids and stacked laminations
  • Magnetic shielding to protect sensitive components from extraneous magnetic fields
  • Magnetic sensors
  • Current sensors
  • Any application requiring high permeability magnetic material, with a low coercive field and low losses, in the range from low frequency up to 1MHz
  • Vacuum chamber vessels and liners
