80/20 Ni Cr 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.
| Nickel-chromium, nickel, ferrochrome alloy wire with electric high temperature oxidation resistance, high strength, not soften and a series of advantages. When used in a long time, the same type and the permanent elongation is very small, which is more Cr20Ni80 alloy with excellent comprehensive properties, is to produce high-quality varieties of choice for electric components. |
