Copper-Nickel Alloys

Copper-nickel also known as cupronickel alloys are widely used for marine appli ions due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability. They have provided reliable service for decades while offering effective solutions to today’s technological challenges.

Types of Copper-Nickel Alloys

High-Strength Copper-Nickel Alloys: The addition of aluminum can increase the strength of copper-nickel by conventional precipitation hardening mechanisms. Cu-Ni-Al alloys, principally consisting of Ni 3 Al and known as gamma prime, are used in shafts and bearing brushes, bolting, pump and valve trim, gears and fasteners.

Copper-Nickel Alloys: Properties, Processing, Appli ions

Cu-Ni alloys are alloys of copper base metal with the largest individual content and nickel with or without other elements, whereby the zinc content may not be more than 1%. When other elements are present, nickel has the largest individual content after copper, compared with each other element.

Cupronickel - Wikipedia

Cupronickel or copper-nickel CuNi is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. The copper content typically varies from 60 to 90 percent. Monel is a nickel-copper alloy that contains a minimum of 52 percent nickel. Despite its high copper content, cupronickel is silver in colour.

Properties of Copper-Nickel Alloys

Properties of Copper-Nickel Alloys Copper-nickels have established properties which show high resistance to seawater corrosion and biofouling. This includes resistance to chlorides in terms of pitting, crevice corrosion and stress corrosion cracking, even in hotter climates.

Copper Nickel Alloys - Alloys with Copper and Nickel

The copper nickel alloys composed of copper with 25% nickel with 0.05-0.4% manganese is commonly used for the manufacture of coins, medals and other semi valuable appli ions.

Copper-nickel alloys Nickel Institute

The main engineering grades of copper-nickel alloys were developed for naval condenser and seawater pipework appli ions. Once their unique combination of high levels of resistance to corrosion, good thermal conductivity and low macro-organism attachment in marine environments was recognised, it led to appli ions in offshore oil and gas, shipbuilding, desalination and power generation.

Resources: Standards and Properties - Copper and Copper .

Copper nickel alloys are very corrosion resistant and thermally stable. The copper nickel alloys contain from 2 to 30% nickel depending upon the appli ion. These alloys usually have additions of iron, chromium, niobium, and or manganese to improve the strength and corrosion resistance.

Copper Nickel Alloys - Industrial Metals

Copper-Nickel alloys are egorized in the C70000 to C72900 numeric range with nickel contents between 3% and 33%. Nickel silvers follow in the numeric sequence C73000 to C79200, but contain no silver having only a silver shine to them.

Copper-nickel Alloys - TWI

Copper and nickel are completely soluble in each other, giving rise to a range of alloys that includes both copper-nickel Cu-Ni and nickel-copper alloys, the latter alloys having been covered in the Job Knowledge articles numbers 107 and 108.
