Mu Metal, a Nickel-Iron-Molybdenum alloy, provides very high initial and maximum magnetic permeabilities and minimal core losses at low field strengths. This vacuum-melted product also offers the advantages of small size and weight in magnetic core and shielding materials.

Mu Metal lamination, made from nickel based alloy (also called Permalloy). With high cost-effective character, now it’s the mainly part of high-end audio transformer, sensor and other sensitive application.

Small components regularly require shielding and HONGER manufactures a wide range of Mu Metal shielding parts for protecting small devices from magnetic interference, such as current transformers, specialist transformers and other discrete components. This type of shield has many uses but is typically used in the automotive, audio and power generation sectors.

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.
