Description
Alloy 70TM-VD is used: for the manufacture of temperature sensors; level gauges liquid helium.
Note
Superconducting precision alloy.
The alloy has a narrow superconducting transition at 4.5 K, the width is not more than 0.2 K, the upper critical field (0,2±0,02) T high specific resistivity of 1.0 μω·m, submenues with temperature (relative change it in the range -16 to +24 To less than 30%). Is made in the form of wire with diameter 0.25−0.35 mm in the copper shell.
