Featured Products

New and highlighted MuMetal products for various applications, please feel free to contact us for more details on any of the items.

High Precision Mu Metal Clock Movement Stator

NiFe-based Permalloy Clock Movement Stator

Made of NiFe based Permalloy, the featured clock movement stator is finely engineered with a high vacuum demagnetization process. Its robust construction ensures lasting durability.

Permalloy Core for HMA Current Transformer

High Metering Accuracy Current Transformer Mu Metal Core

The high permeability 80% nickel-iron, Mu Metal alloy is the material used in the manufacture of high metering accuracy (HMA) current transformer cores. Close control of the magnetic properties over a wide flux density range permits the most conomic design of the transformer for requirements in both ratio and phase angle error.

NiFe-based Permalloy Shielding Box for CT

Nickel Based Mu Metal Shielding Case

Mu Metal Shielding case is a major protecting method in magetic fields, which obtains double actions: one is to prevent or reduce the electromagnetic interference from outer field, the other is to prevent or reduce the part's own electromagnetic field affecting any other relevant parts.

NiFe-based Permalloy Shielding Pipe

NiFe-based Mu Metal Shielding Tube for Current Transformer

Mu Metal shielding tube is a major protecting method in magetic fields, which obtains double actions: one is to prevent or reduce the electromagnetic interference from outer field, the other is to prevent or reduce the part's own electromagnetic field affecting any other relevant parts.

High Permeability Mu Metal Strip for Shilelding

1J85 Mu Metal Strip with High Permeability

Mu Metal, a Nickel-Iron-Molybdenum alloy, provides high initial and maximum permeabilities with low coercive force, low hysteresis loss, low eddy-current losses, and low magnetostriction at low field strengths.

High Permeability Mu Metal Strip for Shilelding

1J85 Mu Metal Strip with High Permeability

Mu Metal, a Nickel-Iron-Molybdenum alloy, provides high initial and maximum permeabilities with low coercive force, low hysteresis loss, low eddy-current losses, and low magnetostriction at low field strengths.

The high permeability 80% nickel-iron, Mu Metal alloy is the material used in the manufacture of high metering accuracy (HMA) current transformer cores. Close control of the magnetic properties over a wide flux density range permits the most conomic design of the transformer for requirements in both ratio and phase angle error.

Mu Metal Gapped Core for Current Transformer

Mu Metal Cut Core for Current Transformer

These Mu Metal Cut Cores are widely used for highly accurate power measurement in power distribution systems, railway networks and large pieces of energy consuming industrial equipment.

Stress Annealed Mu Metal Strip for Toroidal Cores

1J85 Stress Annealed Permalloy Strip for Toroidal Cores

Permally strip (PC) is a soft magnetic nickel-iron alloy strip with about 80 % nickel, 4.2 - 5.2% molybdenum, a saturation induction of about 0.8T, the highest technically obtainable permeability, and a very low coercive force.

Fe-based Nanocrystalline Cores for Power Inverter

Nanocrystalline Cores for Common Mode Choke

Nanocrystalline Core has very high permeability, high saturation induction, low coercivity, low core loss. Suitable for high frequency transformer of inverter welding equipment, solar inverter, and high power transformer in Kw range.
