| Features of production |
On the other 14-1-1187-75 the rods are supplied without heat treatment. Allowed to obtain the desired magnetic properties, the supply of rods in heat-treated according to the mode of the supplying plant, which is specified in the certificate. In the alloy should not be a phase transformation when cooled to a temperature of minus 70°C. Factory-the supplier guarantees the absence of phase transformations without verification. |
| Magnetic properties |
The magnetic properties of the alloy on the other 14-1-1187-75: Magnetic permeability in the field 1400Э: 5,21-6,50 GS/e; Temperature range a linear dependence: -60° - +120° C; Temperature coefficient of magnetic permeability: 0,3-0,7 % in grad. |
