2. Features:
The main feature is its resistivity which is constant over a wide range of temperatures.
Its resistivity is high enough to achieve suitable resistance values in even very small grids, and its temperature coefficient of resistance is not excessive.
In addition, constantan is characterized by good fatigue life and relatively high elongation capability
3:Certificates: ISO9001,ROHS, REACH
4. Applications:
Constantan wire is used chiefly in electrical instruments and and other equipment which can take advantage of its unusual physical property which is that, even over wide variations in operating temperature, its electrical resistance stays at an almost constant value.
