Materials
Tape-wound toroidal and oval cores made of nanocrystalline VITROPERM® or amorphous VITROVAC® offer low losses over the full permeability range between µ~700 to µ >>100,000.
VITROPERM
VITROPERM® is an iron-based nanocrystalline material with an outstanding combination of soft-magnetic properties, making it the state-of-the-art material for a wide range of applications. VITROPERM products are available as ribbon in thicknesses from 14 µm to 20 µm and widths from 2 mm to 66 mm.
Benefits:
- High saturation flux density ≥ 1.2 T
- Permeability can be adjusted in the range from 400 to 800,000
- Excellent thermal stability over a wide temperature range
- Low core losses and low coercivity
- Low or zero saturation magnetostriction
- Highest surface quality of all nanocrystalline materials
Vitrovac
VITROVAC® alloys are magnetically soft but mechanically hard, with a high elastic limit. Properties comprise highest saturation flux density and excellent permeability, making it the ideal solution for applications like electronic article surveillance, flexible antennae, magnetic sensors, magnetic shielding, switching cores in accelerators or power transformers.
Benefits:
- Highest permeability
- High remanence
- Low losses
