CRYOPHY@ alloy for low temperatures

Depending on availability, we supply from stock sheets, foils, round material as well as wire of the following alloys:

A variant of this material is the low-temperature MUMETAL®, called Cryophy®. The alloy, which is similar to material 2.4545, is additionally subjected to a special tempering annealing process in order to score with the highest permeability values even at 4 K. The alloy is also suitable for low temperatures.
