China best selling wholesale copper nickel resistance alloy constantan wire
ELECTRIC RESISTANCE WIRE
COPPER NICKEL ALLOY CONSTANTAN WIRE
1. Brief introduce :
A type of resistance alloy, which is made up of copper and nickel as the main components.It has a low temperature coefficient of resistance (TCR), and a wide operating temperature range (below 500°C). It has good properities on mechanical working, high resistance of corrosion. It is used for variable and strain resistance of corrosion. It is used for variable and strain resisitance elements in alternative instruments.
Cu-Ni Alloy include: CuNi1,CuNi2,CuNi6,CuNi8,CuNi19,CuNi23,CuNi40,CuNi44
We can supply type of : wire,ribbon,strip, customized furnance spring wire/strip
We can supply Size: Wire: 0.001mm-10mm
Ribbon: 0.05*0.2mm-2.0*6.0mm
Strip: 0.5*5.0mm-5.0*250mm
