Nicr60 /15 Flat Nicr Alloy Nchw-2 Storage Heater Nichrome Ribbon Wire
Nickel Chromium Alloy Introduction:
Nickel Chromium alloy has high resistivity, good anti-oxidation properties, high temperature strength, very good form stability and weld ability. It is widely used in electrical heating element material, resistor, industrial furnaces, etc.
A Resistance Alloy used in electrical heating application. It is recommended for use in dry air applications up to 2150 degrees F with good hot strength. It is an alloy of nickel and chromium with high electrical resistance; used for resistance heating elements. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath the wire will not oxidize, preventing the wire from breaking or burning out.
Applications:These elements are commonly found in precision heating applications such as Medical Diagnostics, Satellite, and Aerospace; Electrical appliance industry; Ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements, cartridge elements
