COPPER NICKEL ALLOY - CuNi1
General Description
ELEKTRISOLA copper nickel alloy wire has high tensile strength and increased resistivity values. This makes it the preferred choice for resistance wire applications. Because of the different nickel amount in this product range, the characteristics of this wire can be chosen according to your specific requirements. Copper nickel alloy wire is available as bare wire, or enamelled wire with any insulation and self-bonding enamel. Furthermore, litz wire consisting of enamelled copper nickel alloy wire is also available.
Features
- Higher resistance than copper
- High tensile strength
- Good bending proof performance
Applications
- Heating applications
- Resistance wire
- Applications with high mechanical requirements
- Others
