Abstract
Nickel Aluminium Bronze NAB has been used over the past thrity years as the material of some naval sea water systems. During that time there has been significant problems relating to selective phase corrosion. This has been particularly true with respect to weld heat affected zones, associated with welding, necessitated by the need to repair casting defects. To overcome these difficulties the use of CuNiCr alloys have been suggested. This route has been pursued in the UK and this paper reports the current position with respect to casting supply. It also records some recent corrosion results which have still to be explained.
