Mu Core Metal

Core maximum outside diameter is 35 5 900mm.

Mu core metal.

Magnetic capabilities and mechanical properties of mu metal. It also has very low coercive force hc very low core losses and a low remanence br. 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.

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. More recently mu metal is considered to be astm a753 alloy 4 and is. In addition for very large core requirements these large shapes can be configured and bonded for a number of custom. Mumetal chemical composition in weight nickel ni 80 82 molybdenum mo 3 5 6.

Where cores are required with greater height they can be supplied in two or more. One such composition is approximately 77 nickel 16 iron 5 copper and 2 chromium or molybdenum. Kool mu shapes.
