A metal assembly () suitable for being wound into a coil and used in DC magnet applications. The metal assembly comprises an insulated superconductive wire () extending in a longitudinal direction. The insulated superconductive wire comprises a superconductive wire (), comprising a material () that exhibits superconducting properties within a defined temperature range embedded in a metal matrix (), and an electrically insulating layer () arranged as a coating on the superconductive wire. The metal assembly further comprises a thermal conduction element () comprising a thermally conductive material arranged as a layer at least partly surrounding the insulated superconductive wire, such that the metal assembly, when wound into a coil, exhibits isotropic or essentially isotropic thermal conduction properties.

Metal assembly comprising a superconductor

The invention relates to a welding current nozzle material used in the welding current nozzle for feeding filler material in MIG-type welding. The material used in the welding current nozzle according to the invention is a copper-based alloy where silver is alloyed.
