Soft magnetic alloy has good hot and cold forming properties
The soft magnetic alloy has good hot and cold forming properties. The forging heating temperature is 1120°C, the forging temperature is not lower than 1030°C, the stopping temperature is not lower than 930°C, and the final deformation amount is not less than 15%-20% during die forging. Rolling heating temperature is 1120 ~ 1160 °C, opening and rolling temperature is not lower than 1050 °C, stop rolling temperature is not lower than 930 °C, soft magnetic alloy sheet cold rolling semi-finished products deformation amount is 25% ~ 30%, finished product deformation is not less than 30 %. The quenching temperature in the middle and finished product is 1100°C±10°C [1,8].
