   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, chemical industry, metallurgy mechanism, glass industry, ceramic industry, home appliance area and so on.     Size   wires:0.018-10mm                   Ribbons:0.05*0.2-2.0*6.0mm Strips:0.5*5.0-5.0*250mm       Bars:D10-100mm   Service   1.fine after-sale services
