Amorphous and Nanocrystalline Cores

Nanocrystalline and amorphous cores are made from metallic alloys developed with high technology, granting a particular set of characteristics for these materials. The differential is in it´s alloy amorphous microstructure, a microstructure similar to glass, which is obtained with the use of the melt-spinning technique. By the end of the production process, the amorphous cores remain with a metallic-glass structure, while the nanocrystalline cores obtain a refined structure of nanometric magnetic grains scattered in an amorphous metallic matrix.
Magmattec is the only company of Latin America to produce this type of soft magnetic cores.
