CuNi Alloy Wire CuNi2 Resistance Heating Wire
Copper Nickel 2 s a copper nickel alloy with the addition of Manganese to produce an alloy with a relatively low resistivity but high resistance to oxidation and chemical corrosion. Maximum working temperature is 500 °C. Applications include heating cords and mats
III Main Advantage and Application
A. Physical parameter:
1) Wire diameter: 0.025 ~ 15mm
2) Pure nickel has the ability to withstand relatively high temperatures without deterioration. Maximum operating temperature is approximate 600°C
3) Nickel wire is available in single strand or multi-strand construction. It is supplied from stock either bare, or insulated
B. Characteristics:
1) Excellent straightness
2) Uniform and beautiful surface condition without spots
3) Excellent coil-forming ability
C. Main applications and general purpose:
1) This wire can also be widely used in generally specified for transistor caps, anodes for electronic tubes, leads of electronic components / lead-in-wires for lamps and for wire-mesh. Also used in strip form for various applications including Ni-Cd batteries
2) Also used for cables, Lead-in-Wire for lamps, electronic tube supports, wire cloth electrical connecting leads where temperatures are in excess of those for which copper is suitable, wire weaving
3) Typical applications include: terminations for heating elements as in ovens, plastics extruders, furnaces. Filament supports and lead wires in the lighting industry
