Bronze - where to buy & which alloy?

Which alloy really depends on what you're going to do with it. A bushing might require a different type than a non sparking/ no corrosive valve body. What is your application? Don't take this to mean I know anything about the different alloys, just thinking of what kind of question Mete will ask when he finds this thread.

Aah..... I now see my errors. I meant: for fittings: bolsters, guards, etc.

(Let me guess - beryllium bronze? NOT!!!)
 
I hope Joss doesn't mind but I've got a Piggyback question.

Which to use for a fukos head?

Thanks
 
Fukos or fokos? The hiking axe? If so, should be steel.

FWIW, I got some Aluminum Bronze from Gib. The color is just the coolest. It is closer to a gold color than brass. I have no personal experience what kinda patina it will develop and how corrosion resistant it is, but when polished ... well I like it.
The best web information I found was here.
http://www.cda.org.uk/megab2/corr_rs/pub80/sec1.htm
"Aluminium bronzes are the most tarnish-resistant copper alloys and show no serious deterioration in appearance and no significant loss of mechanical properties on exposure to most atmospheric conditions. Their resistance to atmospheric corrosion combined with high strength is exploited, for example, in their use for bearing bushes in aircraft frames. Aluminium bronzes also show low rates of oxidation at high temperatures and excellent resistance to sulphuric acid, sulphur dioxide and other combustion products and are, therefore, used for the construction of items exposed to either or both these conditions. For example, aluminium bronzes are used very successfully for inert gas fans in oil tankers. These operate under highly stressed conditions in a variable but very corrosive atmosphere containing salt-laden water vapour, sulphurous gases and carbon."

And this:
"Aluminium bronzes preserve their original golden colour for long periods under normal atmospheric exposure conditions which would produce green patination on copper, brass and most other copper alloys. "

Might well be the ideal alloy...
 
If you want to forge them or cast them I'd suggest silicon bronze. It's one of the easier ones to forge, and it's easy to cast because the silicon content makes it self fluxing.
 
Joss, before Gibs offer I was going to get it here: http://www.mcmaster.com/

Search on bronze, there's a page on there that has the alloy types and characteristics.

I really don't know which kind I got, but look at Alloy 954. It seems to come in the dimensions we like.

BTW if it's like the bar I have you take a LOT off the surface to get it smooth, so buy thick.
