I We are manufacturer of heating resistance wire includes
FeCrAL wire, NiCr wire, CuNi wire:
II 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
