Recognizing the need for more precisely controlled stranded wire within the heat treatment industry and working closely with our cable customers, OHMALLOY has developed a range of stranded resistance wire in FeCrAl, NiCr, NiMn and Pure Nickel.
These alloys possess the optimum properties for high performance at elevated temperature and in other adverse conditions where reliability and quality is of the paramount consideration
