Stranded Resistance Heating Wires

• Since the heat treatment industry requires more precisely controlled stranded wires, we have developed a range of stranded resistance wires made of nickel-chromium alloy and pure nickel wire. It is usually bundled together by 7, 19 or 37 resistance wires. We are able to meet the requirements of any customer, and we always put quality and precision first. The standard resistance tolerance is +/- 5%, and tighter resistance tolerances are also available upon request.
