constantan wire 6J40 Cuni40 electric resistance alloy constantan wire

III Main Advantage and Application 

A. Physical parameter:

 1) Wire diameter: 0.025 ~ 0.20mm
 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
