1J50
This alloy has a narrow and steep hysteresis loop, a large magnetic permeability and a small coercive force in a weak magnetic field, so it has wide applications in transformers, magnetic shields, magnetic heads, aerospace precision control instruments and other fields. application. At the same time, 1J50 alloy has good processing performance and can be made into various components with complex shapes and precise size requirements. Therefore, it is often used as precision magnetic components in the aerospace field.
