VITROPERM

Like amorphous materials, the nanocrystalline VITROPERM® alloys are manufactured using rapid solidification technology.

VITROPERM is an amorphous material in the beginning stages of the manufacturing process. In order to produce the nanocrystalline two-phase structure, the amorphous circular tape cores are tempered at about 550 °C (1022 °F).

The two-phase structure is characterized by a fine crystalline grain (mean diameter 10-20 nm), which is embedded in an amorphous residual phase. This structural feature is responsible for the VITROPERM material achieving highest permeabilities and lowest coercitivity field strengths.

In addition, low tape thickness (about 20 µm) and relatively high electrical resistance (1.1-1.2 µΩm) ensure the lowest eddy current losses and an excellent write-read response in the permeability of the alloy. The combination of these properties together with a saturation induction of 1.2 T and favorable thermal properties, result iin VITROPERM being a state-of-the-art material. This alloy is equal or superior to ferrites, permalloys and amorphous materials based on cobalt.
