Soft magnetic alloys are materials that can be easily magnetized, thus exhibiting high permeability, and just as easily demagnetized. High permeability allows the design of smaller, more efficient magnetic parts. Several factors have a bearing on the soft magnetic alloy choice. One external factor is corrosion resistance, which is essential for devices exposed to weather or other corrosive environments. The most important magnetic criteria to consider are sensitivity (permeability) and strength... (read more)Browse Datasheets for Qingdao Eversun Precision Manufacture Co., Ltd.
