Mu metal sheet uk. Typical properties of magnetically annealed mu metal grade astm a753 alloy 4. Hydrogen or vacuum heat treatment which method is the best. Mu metal is a unoriented nickel iron soft ferromagnetic alloy with very high permeability suitable for sensitive electronic equipment shielding. It has several compositions.

Mu metal foil is typically used in delicate applications within the low frequency range where sensitive devices are impaired by magnetic interference. Magnetic shields are a leading supplier of magnetic shielding sheets. Based in kent england our manufacturing facility is fully equipped with the latest technology to provide our customers with the highest level of service and quality. Mu metal is a 80 nickel 4 5 molybdenum balance iron soft ferromagnetic alloy which means that it does not retain a field after the removal of an external magnetizing force.

Mu metal offers exceptionally high initial and maximum permeability with minimum hysteresis loss.
