Locally stocked length is usually 13" and it's sold at a surprising number of places at reasonable prices (to me anyway), mainly because I don't have to buy 10 feet! This alloy is typically Cu83 Pb7 Sn7 Zn3. I've used it regularly for boiler bushings larger than 5/8"OD (I have PhosBrz up to 5/8") and the 7% lead content seems to have no effect at all on the (silver) solderability when properly prepared nor does it lead to dezincification. I did check this last issue with the mfgs and found that at this level of Zn content it is not a "brass" and dezincification is not a safety issue.
