Our nanocrystalline core is suitable for different applications of electric current measuring, as it has good linearity and low iron loss over wide-range of frequency. With much lower price than permalloy, Xianyu’s high initial permeability nanocrystalline cores can be used for high sensitivity measurement and current moniter.
As important components of current transducer, our nanocrystalline cores are widely used for current transformers, rectifier transformers, rectifier transformers, flux detectors, pulse transformers, ammeters, modular meters, electrical and electronic testing devices, and so on.
With more than 15 years experience, we can design and manufacture customized cores of excellent magnetic properties. We can make tiny nanocrystalline cores with ID (inner diameter) less than 5mm, or large cores with ID more than 500mm. In order to get different magnetic parameters, we treat these cores by different annealing processes, with or without external magnetic field. Due to our fast prototype technology, we can provide OEM samples within a couple of days.
The most common shape of nanocrystalline core is toroidal or round, as it has nearly no flux leakage and can be easily made by winding the thin ribbon. As we manufactured these tape-wound bushing type cores by automatic winding machine, we can provide low price for qualified products make quick delivery for large scale production. We can also provide nanocrystalline cores with winding coils. The production process of nanocrystalline cores is introduced as below post.
