Since the e-Co alloy forms a homogeneous solid solution and these elements suppress the formation of a regular lattice, it is thought that the movement of domain walls becomes easy and a soft magnetic alloy with a small coercive force is obtained.

The reason why one or more of r, Mo, W, V, Nb and Ta is limited to a total of 0.1 to 10% and the balance is Fe is due to its composition as is clear from each example, Table 3 and the drawings. Alloys in the range are easy to process and have a magnetic flux density l3so of 16 kilogauss or more and a coercive force of 2 oerste.
It has a specific electrical resistance of 7 degrees or less and a relatively small coefficient of thermal expansion, making it suitable as a dry/wet magnetic alloy for the reed pieces of reed switches that require glass sealing. However, if the Co content is less than 20% or more than 65%, the coefficient of thermal expansion will be large, and the alloy will break during glass sealing, making it unsuitable as a soft magnetic alloy for lead pieces.
