Mu Core 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.

Mu core metal.

Core maximum outside diameter is 35 5 900mm. Kool mu shapes. Mu metal offers exceptionally high initial and maximum permeability with minimum hysteresis loss. Kool mu shapes e cores toroids u cores eq cores lp cores eer cores and blocks are available in various sizes.

Magnetic capabilities and mechanical properties of mu metal. Mumetal chemical composition in weight nickel ni 80 82 molybdenum mo 3 5 6. One such composition is approximately 77 nickel 16 iron 5 copper and 2 chromium or molybdenum. These shapes compare favorably with gapped ferrites powdered iron and silicon steel cores.

Available as stress annealed soft annealed for ease of fabrication or final annealed for maximum permeability. 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.
