Abstract
The use of a Copper Nickel Chromium Alloy to replace the current Nickel Aluminum Bronze in naval seawater systems and other marine applications is being pursued in the UK. This has been principally implemented to avoid the selective phase corrosion problems encountered in NAB, but other advantages may exist. This paper will present details of recent studies conducted in the uK on the Copper Nickel Chromium alloy to NES824. A series of full sized cast components have been procured to confirm the supply of seawater system components. The acceptability of these components for naval use has been established through chemical analysis, mechanical property tests and non destructive testing. Destructive evaluation of one component has been conducted to compare properties with the test bars separately cast but used in the acceptance documentation.
