Depending on the availability we ship from stock flat material, round material, foil and wire of the following alloys:
Around 80 % Nickel
µMetal, ASTM A753 Alloy 4, alloy 2.4545
A variant of the material is the low-temperature suitable µMetal, called Cryophy®. The alloy, which is similar to the material 2.4545, is additionally subjected to a special annealing process in order to be able to score with the highest permeability values even at 4 K.
Semi-finished products – cold-rolled, strip-annealed – available from stock
* Thickness tolerance +/- 5%. Other dimensions on request.
Typical mechanical properties after annealing
