Copper-Nickel-Alloys
Brief description
Copper and nickel are miscible due to their crystal structure.; the whole alloy area shows a single-phase, face-centered cubic lattice. With an increased nickel content the red colour of the copper turns into the bright silvery of the nickel. The same applies to the magnetic property. The ferromagnetic range of this alloy group starts at about 40 % nickel content. The electric resistance reaches its maximum of approx. 0.5 µ Ohm* with about 50 atomic-% nickel. Another particularly important property for application is the high chemical resistance. In oxidizing media the nickel is passivated, which grows with increasing nickel content. This effect can even be intensified by adding manganese and iron to the alloy.
Applications
•Heating resistor materials, e.g. as heat conductor in thermal switches, resistors in electrical engineering
•Corrosion-proof materials, e.g. in gas-level indicators (requirement: not ferromagnetic); seawater pipelines (insensitive to cavitation), tanks in the chemical industry, oil coolers for ship engines, for seawater desalination plants and sewage treatment plants
•Coinage materials, e.g. 25 Cent, USA and 1 and 2 Euro-coins
•Cladding and intermediate layers for clad strips
