Mu Core Metal

Where cores are required with greater height they can be supplied in two or more.

Mu core metal.

Available as stress annealed soft annealed for ease of fabrication or final annealed for maximum permeability. Magnetic capabilities and mechanical properties of mu metal. However cores may be supplied up to 47 25 1200mm diameter with reduced magnetic performance subject to a minimum build up limitation of 5 of the diameter. These shapes compare favorably with gapped ferrites powdered iron and silicon steel cores.

More recently mu metal is considered to be astm a753 alloy 4 and is. One such composition is approximately 77 nickel 16 iron 5 copper and 2 chromium or molybdenum. It also has very low coercive force hc very low core losses and a low remanence br. Mu metal is a nickel iron soft ferromagnetic alloy with very high permeability which is used for shielding sensitive electronic equipment against static or low frequency magnetic fields it has several compositions.

Mu metal offers exceptionally high initial and maximum permeability with minimum hysteresis loss. Core maximum outside diameter is 35 5 900mm. Kool mu shapes.
