Product Description

Constantan alloy wires:

Constantan is a copper-nickel alloy usually consisting of 55% Copper and 45% Nickel. Its main feature is its resistance which is constant over a wide range of temperatures. It is also called Alloy 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 44, CuNi 44, CN49.

constantan alloy wire: konstantan alloy wire:
1.selected first-class raw materials
2. adopt advanced production technology
3.quality assured
Constantan is based on copper-nickel as the main component of the resistance alloy. Characteristics: with a lower temperature coefficient of resistance, the use of a wide temperature range (500 degrees Celsius) good machining properties, corrosion resistance and easy soldering. Thermoelectric power of high copper, the exchange of instruments can be made of the variable resistors and strain resistive element.

Mainly uses in the electric car controller, the instruments and meters, the integrated circuit, the sample electric current, the resistor. And low pressure resistance and so on.

nature : with 40% nickel, 1.5% copper manganese alloy. With a low temperature coefficient of resistivity and Medium Resistivity (resistance rate of 48 μΩ cm). In a wide temperature range. A good processing properties and welding properties. In exchange circuit suitable for use for precision resistors, slip resistance, resistance strain gauges, but also can be used for thermocouples and thermocouple wire material compensation.
