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.
Cobalt-iron alloys, CoFe, have the highest saturation polarization of all soft magnetic materials of around 2.35T.
Material 1.3981, better known under the brand name KOVAR®, is an iron-nickel-cobalt alloy with a very low coefficient of thermal expansion.
Material 1.3912, better known under the brand name INVAR®, is an iron-nickel alloy with an abnormally low coefficient of thermal expansion
Technically pure iron, material 1.1003, is defined by a degree of purity of 99.8 to 99.9%.
This group includes materials that combine a relatively high saturation, high permeability values and low coercive field strengths.
µMetal, ASTM A753 Alloy 4, alloy 2.4545. An alloy that contains nickel as its main component.
