Metglas & Nanocrystalline

US $200.00



Metglas and Nano materials are thin amorphous ribbons that use more silicon than electrical steel (typically 9 to 15%) to reduce core loss further. They are produced by cooling a molten metal over a rotating copper drum.  Metglas offers low core loss in 1000 Hz to 20,000 Hz range while Nano materials extend the range to 100,000 Hz. The thickness of the ribbon is about 0.001 inch; its width can be upto about 6 inches. They can be supplied in ribbon rolls, but users should preferably purchase the toroids, C cores etc made by the manufacturer since their properties are sensitive to stress and annealing. They are generally used to build single phase transformers and inductors.  

MagWeb’s Metglas & Nano Folder has 56 excel files listing magnetic properties of these materials, produced by 4 manufacturers.  Of these, 30 files contain B(H) magnetization curves/permeability curves while 26 files contain core loss curves.  For a full list of commercial names of all these materials, please click on List of Materials – Metglas & Nano  

Version 5 also includes a DIGEST file that contains discrete magnetic properties of all these materials in a single excel file.

By downloading this folder you will have 56 files on magnetic properties of all Metglas and Nanocrystalline materials produced world wide at your finger tips!. 

Please review the Handbook for more technical information on the magnetic  properties of these novel materials.
