Nanocrystalline Alloy Strip as Transformer Material

Product Description

Product Type: Strip Carbon Content: Low Carbon Brand: Ualloy Trademark: Ualloy Material: Fesib Product Name: Nanocrystalline Alloy Strip as Transformer Materia Application: as Transformer Material Origin: Hangzhou, China Nanocrystalline Alloy Strip as transformer material 


 Application area:
l Switch power transformer and Pulse transformer iron core
l Power transformer , precision current mutual inductor iron core
l Leakage protection switch mutual inductor iron core
l Filtering inductance, storage inductance, the electric reactor iron core
l EMC common mode inductance and differential mode inductance iron core
l Saturable reactor, magnetic amplifier, Spike killer, Pulse Compressor iron core and magnetic bead
 
Features:
l High Saturation magnetic induction - reduce transformer volume
l High magnetic permeability low coercive force- improve transformer efficiency, mutual inductor sensitivity, reduce coil distribution parameters
l Low loss- reduce transformer temperature rise
l Good temperature stability -  under 130ºC for long-term work
l Lower price -  has the best cost performance of all the metal soft magnetic material
