Alloy, based optionally on: Fe, FeNi, Co, nanocrystalline (Fe, Si, Cu, Mo, Nb, etc.)
It all depends on the alloy
The ribbons are suitable for use in a range of applications, depending on the alloy used. What they all have in common are their excellent magnetic properties. The microstructure of the alloys is amorphous due to the high quench rate. If the ribbon undergoes further temperature treatment, its structure changes into an ordered arrangement of atoms, nanocrystalline.
High electrical resistance
Heat- and corrosion-resistant
The individual strengths and weaknesses of the alloys – Fe-based alloys, FeNi-based alloys, Co-based alloys, nanocrystalline alloys – can be found in the data sheets. Alternatively, our experts will be pleased to provide you with advice.
Different alloys available
Amorphous and nanocrystalline ribbons and products differ in the materials used and, in the case of the nanocrystalline alloy, also in the production process. Accordingly, the strengths of the individually alloys differ.
Amorphous and nanocrystalline ribbons and products
Fe-based alloys: Fe, Si, B, C, P, etc. Their outstanding property is their high level of magnetism. Permeability, core losses and other soft magnetic properties are significantly better than those of silicon iron. Additionally, this material is more cost-effective.
FeNi-based alloys: Fe, Ni, Si, B, P, etc. Weaker magnetism, relatively expensive material, but high permeability.
Co-based alloy: Co, Si, B, etc. Lower magnetic properties, but high permeability.
Nanocrystalline alloys: Fe, Si, B, minimal amounts of Cu, Mo, Nb, etc. Cost-effective material with excellent magnetic properties. Even though no expensive Co is mixed in, in certain areas it can have the same outstanding performance as Co-based amorphous alloys.
The uses of amorphous and nanocrystalline ribbons
As you can see from the specifications, the properties depend on the production process and above all the alloy.
