From what I found: There is the leaded naval bronze: Sn=6.0%, Pb=1.5%, Zn=4.5%, Cu=88%(Sn for tin,Pb for lead,Zn for zinc, Cu for copper) and the "non leaded bronze" with less lead. This alloy is called in fact Naval Brass or C46400. Here's a data sheet:http://www.atlasbronze.com/C46400_product_sheet.html
I polished allot of that brass back in my day in the US Navy.
