Principal Design Features Copper Nickels (Copper-Nickel), Copper-Nickel, (90-10). Excellent corrosion resistance, especially in marine environments. Moderately high strength, good creep resistance at elevated temperatures. Properties generally increase with nickel content. Relatively high in cost compared with copper-aluminum and other alloys with similar mechanical properties.


Applications Copper-nickels are mainly used for seawater service as forged and machined valve and pump components, fittings and hardware. Used where high corrosion resistance is required and where concern over chloride stress-corrosion cracking prevents use of stainless steels.


Machinability The machinability rating of this alloy is 20. (Where Alloy 360 FC Brass is 100).


Welding Soldering of this alloy is rated as “excellent”, brazing is rated as “excellent”, oxyacetylene welding is rated as “fair”, gas shielded arc welding is rated as “excellent”, coated metal arc welding is rated as “good”, spot welding is rated as “good”, seam welding is rated as “good”, and butt welding is rated as “excellent”.
