General Description
Due to has high tensile strength and increased resistivity values, TANKII copper nickel alloy wires are the first choice for applications as resistance wires. with the different nickel amount in this product range, the characteristics of the wire can be chosen according to your requirements. Copper nickel alloy wires are available as bare wire, or enamelled wire with any insulation and self-bonding enamel. Furthermore, litz wire made of enamelled copper nickel alloy wire are available.
Features
1. Higher resistance than copper
2. High tensile strength
3. Good bending proof performance
Application
1. Heating applications
2. Resistance wire
3. Applications with high mechanical requirements

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.
