COPPER ALLOYS IN THE MARINE ENVIRONMENT

Highlights new prototype development work using copper- nickel alloys for vessel hulls and seawater intake piping systems. Initially, maintenance-free performance and economies that can be realized through the use of copper- nickel alloys in salt water environments are described. Data presented shows performance of copper alloys under one of the most severe working conditions within the seawater system. The data was developed in performance studies of a copper-nickel-hulled fishing vessel during four years of operation. Savings resulting from the antifouling and corrosion resistant characteristics of the materials are discussed. Also covered is performance of dissimilar metal combinations in seawater. The second part concentrates on methods of construction with copper-nickel, copper-nickel- clad to steel and lamination to concrete structures. Details are given on attachment of large copper-nickel plates to steel framing and protection of this system from galvanic corrosion. Discussion also includes welding techniques and procedures for all position field welding of solid copper-nickel and copper-nickel-clad steel.
