Introduction:
Hemei Electronics supplies Cut cores in soft magnetic Nickel alloy material to industries requiring High accuracy flux Concentrator used in current sensing application. Depending on the application, customers can select suitable Nickel or Silicon Iron alloy. We manufactures Cut cores in Toroid and Rectangular shape. The cut cores are made robust by finishing them with varnish coating.
Alloy punched sheets can be customised

Be familiar with the shielding mechanisms of various materials, and understand the characteristics and applications of various magnetic and metal materials
Application:current transformer, inductor, choke coil, etc.
Commonly used alloys are 1J50, 1J79, 1J85 and so on. The saturation magnetic induction of 1J50 is slightly lower than that of silicon steel, but its magnetic permeability is dozens of times higher than that of silicon steel, and its iron loss is also 2 to 3 times lower than that of silicon steel. It is made into a transformer with a higher frequency (400~8000Hz), and the no-load current is small. It is suitable for making a small high-frequency transformer below 100W. 1J79 has good comprehensive performance and is suitable for high frequency and low voltage transformers, leakage protection switch cores, common mode inductance cores and current transformer cores. The initial permeability of 1J85 can reach more than 100,000 105, which is suitable for low-frequency or high-frequency input and output transformers, common mode inductors and high-precision current transformers with weak signals.
Hemei Electronics produces magnetic cores and raw materials of various types and materials, with mature processing technology and reliable product performance. If you need products in this area, please feel free to contact us!
