Copper Nickel Alloy Foil Constantan Strip/CuNi40 Tape/ CuNi44 Alloy foil 0.05x300mm
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.

Application of Constantan
Constantan is a copper-nickel alloy that contains specific minor amounts of additional
elements to achieve precise values for the temperature coefficient of resistivity. Careful
control of melting and conversion practices results in a very low level of pinholes at
ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges.
