Mu Core Metal

Kool mu shapes e cores toroids u cores eq cores lp cores eer cores and blocks are available in various sizes.
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 metal offers exceptionally high initial and maximum permeability with minimum hysteresis loss. In addition for very large core requirements these large shapes can be configured and bonded for a number of custom. Kool mu shapes.
Magnetic capabilities and mechanical properties of mu metal. Mumetal chemical composition in weight nickel ni 80 82 molybdenum mo 3 5 6. It also has very low coercive force hc very low core losses and a low remanence br. Available as stress annealed soft annealed for ease of fabrication or final annealed for maximum permeability.
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. Where cores are required with greater height they can be supplied in two or more.
