Constantan Wire
 
Constantan, New Constantan and Manganin are resistance alloys with copper as the basic elements. They have low resistance temperature quotieties, wide range of work temperatures, good mechanical processing performances and corrosion prevention. Being easy in braze welding, they are applicable to manufacturing various resistors, splitters, alternating-current meters as precise resistance components of rheostat resistance and strain resistance.
