    CuNi40 Cuprothal 294 Copper Nickel Alloy Constantan Strip CuNi40 / CuNi44 Constant Size 0.005mm * 100mm

     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.
