Alloy Powder Cores

$200.00

Product Description

Alloy Powder cores are made of iron alloy powders mixed with epoxy resins, which is compressed at high pressure to form toroids, pot cores etc. Their permeability ranges 10 to 600 and saturation flux density ranges 0.7 to 1.6 T.  They are mainly used in inductors and transformers in power electronics industry.

Of these, MPP (made from 80% Ni Steel powders) offers lowest core losses, but has lower flux capacity (Js ~0.75T). Xflux (made from high Si steel) has the highest saturation flux density (Js~ 1.6T), but produces highest losses. Amoflux (made by powdering Metglas ribbon) offers 50% lower loss than HiFlux (made from 50% Ni Steel).   Most alloy powder cores can operate up to 200 C, excepting Amoflux which is limited to 155 C.

Several firms produce powder cores of same composition. But the coreloss and B(H) curves are sensitive to trace impurities, even if the composition is same. So MagWeb lists the properties of alloy powder cores produced by each firm, irrespective of they being of same composition.

The “Alloy Powder Cores” folder contains 28 smooth B(H) Curves and 43 Digital Core Loss Curves (total of 71 excel files).  By downloading this folder you will have magnetic properties of all alloy powder cores manufactured world wide at your finger tips!  

Please review the User Manual for more information and a list of all alloy powder cores contained in this folder. 

This website is designed for immediate download of folders via credit card. If you wish to purchase via quote/purchase order, please email to rao@magweb.us
