"Aluminium Bronze"

Question:

"Could you please comment on the suitability of Aluminium Bronze subject to seawater containing dissolved sulphur dioxide and sulphurous acid. Temperature is around 21 degrees C and pH varies between 2 and 3."

Answer:

The application is important in that practically all of the copper alloys possess modest to unacceptable resistance to sulfur compounds, including SO2. Therefore, anticipated corrosion rates are important with respect to whether the component has a thick cross section (valve disk) or a thin one (exchanger tubes). Even with a thick cross section component as a valve disk, the continued ability to maintain a seal is important and potentially life limiting; therefore, the seal area must be considered. I would consider carefully before specifying a copper alloy for seawater containing substantial dissolved SO2. For more information, please refer to our extensive corrosion database on copper alloys in the Reference section of our website at http://www.hghouston.com/coppers/copper.html.
