Abstract

Wires or bands of magnetic alloy for employment in constructing electrical equipment which in use involves the effects of small magnetic fields have a thickness not exceeding 0,03 mm. and are incompletely annealed after a preceding cold working in order to improve the constancy of permeability under working conditions. The incomplete annealing consists of a heat treatment carried out at such temperature and for such time as will modify the magnetic properties of the material appreciably, but not to the extent obtained by heating above the critical temperature. This temperature is usually below 500 DEG C., and is frequently 400 to 425 DEG C., and the duration of the treatment is usually a few minutes, but may be made longer if lower temperatures are utilized. Specifications 260,039, [Class 72], and 343,179, [Group XXXVI], are referred to.
