Vinegar in the toilet

I think that if your bronze is a 'nice pink' it means that it's become depleted of zinc...?

[/ QUOTE ]If your 'bronze' has become depleted of zinc then it was brass, not bronze.

Now we're going around in circles. Manganese bronze is brass with about 2% manganese. See further up. 'Tin bronze' propellers are rare and very expensive.

[/ QUOTE ]I thought we were discussing toilets and seacocks? Or are you saying that most seacocks are brass?
 
Sorry, mixing up threads!

But yes, most seacocks and skin fittings are brass. Even Blakes have been DZR for quite a few years now, I guess they were a tin bronze once. Many sold in chandleries are Tonval, which is a bog-standard brass.
