Uses
​
-
Machinery and piping used for oil and chemical processing.

Weldability
​
Nickel-Copper Alloys are generally weldable via GTAW welding, but SMAW is preferred for R-405 as it is less affected by the Sulphur content.
Machinability
​
Nickel-Copper Alloys are a little difficult to machine as they work harden very quickly. Alloy R-405 was specifically developed with the addition of Sulfur to make it more readily machinable.
