Copper Alloys in Seawater: New Publication Launched
Marine
engineer, corrosion, marine, copper-nickel

A new technical publication has launched this week at NACE’s Corrosion 2016: ‘Copper Alloys in Seawater: Avoidance of Corrosion Problems’, by Roger Francis. The guide has been written principally for marine, mechanical and other engineers who have to select materials of construction but do not have a corrosion background.

Copper alloys have been widely used in seawater and related brines, such as in thermal desalination plants, for many years, generally with excellent results. They are commonly used for piping, valves, pumps and heat exchanger tubing, but have found many other applications. 

Occasionally, there are failures due to corrosion, and in many cases these could be avoided by following some simple design recommendations, selecting an alternative copper alloy, or using a basic preventative strategy. This document covers the most common types of corrosion and shows uncomplicated methods to avoid them. If these are implemented at the design stage, optimum service lives can be achieved and unnecessary expenditure avoided.

The guide is available online and at Booth 539 of NACE International’s Corrosion 2016.

Copper Development Association is a non-profit organisation that promotes and supports the use of copper based on its superior technical performance and its contribution to a higher quality of life. Its services, which include the provision of technical advice and information, are available to those interested in the utilisation of copper and copper alloys in all their aspects. The Association also provides a link between research and the user industries, and is part of an international network of trade associations: Copper Alliance.
