HP-70TM
The alloy has a narrow superconducting transition at 4.5 K, a width of not more than 0.2 K, an upper critical field, (0.2 ± 0.02) T with a high specific electrical resistance of 1.0 μOm · m weakly changing with temperature in the range from -16 to +24 K does not exceed 30%). It is made in the form of a wire with a diameter of 0.25−0.35 mm in a copper sheath.
For the manufacture of temperature sensors; of level of liquid helium.
