STA Cr20Ni80 resistance heating wire and resistance wire same with Nikrothal in quality, Cr20Ni80 nickel chrome Resistance Alloys in Wire, Bar, Strip, Ribbon forms. These are ferromagnetic alloys whose electrical resistance properties are similar to those of the Nickel-Chromium alloys, making them suitable for electrical heating applications.

 

Round and Nichrome Cr20Ni80 resistance heating wire and resistance wire with bright annealed or oxidized surface, depending on size. Round resistance wire sizes up to 0.40 mm (0.0157 inch) are available with insulation and coating. STAA Cr20Ni80 resistance heating wire and resistance wire is characterized by consistent resistivity from delivery to delivery, facilitating trouble-free production.

 

Cr20Ni80 Resistance heating alloys and resistance alloys

The wide Cr20Ni80 range of resistance heating alloys and resistance alloys in wire form makes it possible to select the most appropriate grade and size for each respective application, resulting in optimum end-product performance.
