Failure of Silicon Bronze Impeller from Dealloying Via ...

14/08/2013  A cast silicon bronze (UNS C86700) impeller that had been severely corroded was submitted for failure analysis. The customer had informed that this impeller was used to pump potable water, but the service length and chlorine content of the water were unknown. The impeller displayed a Cu-rich red phase on its surfaces and showed a pattern very similar to dezincification. Further

Brasses and bronzes – Cox Engineering

‘Bronze’ rigging screws may be made from either silicon or aluminium bronze. Aluminium and nickel-aluminium bronzes are widely used for ship’s propellers but the alloy seems to have fairly limited use for this purpose in yachting applications. Brass-based bronzes. Brass is also copper-based but there the similarity ends. Its main alloying element is zinc, at anything between 0 – 50% ...

Boiler dezincification - modelengineeringwebsite

I found some bronze in my box of brass and made a new clack valve from bronze bar (see photo). The main body was made from phosphor bronze which turned easily but was a devil to drill, apparently tallow lubricates well but probably not a good idea if the parts need to be silver soldered. The last step was to silver solder the two parts together and this went well.
