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.
