Description


CuNi alloy resistance constantan flat wire


 


CuNi resistance alloy 
World class standard 
Stable and uniform properties 
Solid bare copper conduct


 


As a big manufacturer and exporter in China on the line of electric resistance alloy, we can supply all kinds of electric resistancealloy wire and strips (resistance steel wire and strips weiding wire)


 copper nickel alloy includes : Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23CuNi30, CuNi34, CuNi44.


 


1. constantan 


Product Details: 
Grade: 6J40 also known as cuni40
Nature: With 40% nickel, 1.5% copper manganese alloy 


 


Constantan is 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.


 


Our products have the following features: Stable performance, high resistivity, high working temperature, allowable high surface load, small specific gravity and reasonable price. 


 


2. constantan dimension available


 


Wire: 0.018-10mm  Ribbon/ flat wire: 0.05*0.2-2.0*6.0mm
