Cr20Ni80 bright soft resistance wires
- Features:
- 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
- Advantages:
- 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.
- Specifications:
- 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
