Duo-Twist™ cryogenic wire is a single twisted pair of 32 AWG phosphor bronze wire, twisted at 3.15 twists per centimeter, with polyimide insulation. It is non-ferromagnetic and designed to minimize electromagnetic noise pickup in cryogenic sensor applications. The wire has a diameter of 0.203 mm and is rated for 77 K and 305 K vacuum fuse currents of 3.1 A and 4.02 A respectively. It has a thermal conductivity of 48 W/(m·K) at 293 K and an electrical resistivity of 11 µΩ·cm at 293 K.
Lake Shore manganin wire is often used for cryostat wiring or heater requirements in nonmagnetic applications.
