Cr20Ni80 Resistance Wire is an alloy used at operating temperatures up to 1200°C (2200°F). Its chemical composition gives good oxidation resistance, especially under conditions of frequent switching or wide temperature fluctuations. This makes it ideal for a wide variety of applications including heating elements in domestic and industrial appliances, wire-wound resistors, through to the aerospace industry.
Cr20Ni80 Resistance Wire is also known as Nichrome V, Tophet A, Alloy A, Brightray C, Cronix 80, Nikrothal 8, Chromalloy, Chromel A, and Gilphy 80, N8, HAI-NiCr 80, Resistohm 80, Protoloy, MWS-650, Stablohm 650
It has stable structure, stable electrical and physical properties, good mechanical properties at high temperature, good cold deformation plasticity, good weldability, long-term use without brittle fracture and strong oxidation resistance.
Bright and soft annealed finish: 0.03 - 1.6mm; Acid-pickled finish or primary color (dark green): 1.0 -10.0mm; Rods: 8.0-22.0mm
Flat wire: width from 0.2 - 6.0mm and thickness from 0.08 - 1.0mm; Wide strip: width from 8.0 - 240mm and thickness from 0.05 - 4.0mm
