I just got a load of brass or bronze flat bar,that came out of an old chandlery- ie a place that sells equipment for boats,
I didnt get any paper work certs with this as it is old and the company out of business, this should be a marine type bronze alloy , but before i go sticking it near anyhting marine , I need to guesstimate what it is , so does anybody have any idea as to identifying yellow metal alloys?thanks

Suggest you try your local recycleing yard. At least in my area they will tell you the composition of the metal (very little cost if any). or you can send in a dime size piece to get certs (thirty five to eighty dollars).

A real analysis is likely expensive... but you can get a good idea w/ a bit of home chemistry. Check out http://recyclebiz.com/DoD%20Metal%20Testing%20Manual.pdf for some useful tips....

admiralty brass, aka dzp brass would be my first bet try 'LDM G563'

[its an alpha brass with a smattering of Sn to keep the effects of salt at bay]
the density can be calculated, thats a reasonable guide if you have a balance available, colour is a clue look up copper phase diagram on wiki
