OHMALLOY have 15 years in producing the nichrome stranded wire for ceramic pad heater. The normal size is 0.52mm*18+0.57mm*4, 0.55mm*19, 0.2mm*7, 0.3mm*7... We also can make the bunched wire as per client’s special requirment.
The available conductor nichrome wire is as following sheet.

We also can use the nickel wire, copper wire, NiMn wire as conductor material.
Performance:High resistivity,good oxidation resistance,very good form stability,good ductility and excellent weldability,high temperature resistance.
Application:A heating element repair kit comes with 80/20 (19 multi-strand), in addition, Heater Core Wire is Consists of 80/20 nickel chrome alloy (19 multi-strand) on 500m/1640' roll.
Nichrome Stranded Wire is not always 19 multi strand,we can also produce it upon your request.
