Various high-permeability nickel alloys are available. They include the popular MuMetals. These alloys contain a combination of manganese, copper, and chromium. The resulting combination of metals increases the permeability while reducing the hysteresis losses. They are also used as base materials for optical instruments.
Nickel 205 is used for anodes, base pins, getter tabs, and cathode shields. It is also used for structural parts of tubes. Its magnetostrictive coefficient is high, making it an attractive material for cathode shields.
Nickel 270, on the other hand, is a substrate for precious metal cladding. It has greater ductility, compared to nickel 205, and is especially useful for hydrogen thyratrons. Its high permeability and ductility make it a desirable candidate for use in a variety of applications.
Nickel 205 has been used for base pins, anodes, and grid side rods. It has a high Curie temperature, and a 0.005% limit on iron. It has been used for cathode shields and base pins in speedometers. It has also been used in the production of magnets.
