Composition

​

40-67% Nickel, 24-34% Copper, the balance is comprised of Iron, Manganese, Carbon, Silicon and traces of Aluminium and Titanium.

Common Shapes

​

Nickel-Copper Alloys are commonly available in

​

• Sheets and Plates

• Welded & Seamless Tubes and Pipes 

• Wire

• Bar

• Fittings

​

(Not all alloys or tempers available in all shapes)

Characteristics

​

• Good Workability

• High corrosion and weathering resistance in many demanding environments including sulfuric, hydrofluoric and seawater.

• Excellent subzero mechanical properties 

• Ductile- easy to draw

​

Uses

​

• Machinery and piping used for oil and chemical processing.

• Pollution control equipment

• Marine applications

• Heat exchangers

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.
