We offer many different alloys for you to choose from. This page, in particular, is dedicated to giving the specifications for Tin Bronzes. The ingot numbers that you find listed in the furnace room pages, such as Tin Bronzes, are the alloys that we have found to be the most popular, and are arranged in three main categories (Bronze, Aluminum, and Zinc.) We have an inventory of each of the alloys listed in the furnace room pages, while other alloys are available on request.
(Tip) Please keep in mind that each alloy is engineered for a particular purpose. For example, sheet metal can require different characteristics of an alloy than tubing, extruded metal or sand casting . Because certain projects require different alloy characteristics, we certify our alloys. Not all foundries offer alloy certification, and some cast their parts from mixed alloys of scrap. This can greatly weaken an alloy, or make it unpredictable. If you have a particular purpose, such as needing the full strength of your metals property's with predictable result's, then certified material is crucial. At Barr Casting we keep a record of the certifications for each new bundle of ingot.
Please note: In the designation
system, numbers from C1000 through C7999, denote wrought alloys. Cast
alloy UNS No. numbers start at C80000 through C99999

The tin bronzes are the true bronzes, which are basically alloys of copper, tin lead and some times zinc Because of their good mechanical and corrosion resistance ,these alloys are often used in castings subject to liquid or gas pressures, as in valves and pumps, etc.
Major uses: valves Fittings, Bearings, Pistons, Gears, Steam Castings, Bushing, Pump Impellers. Nuts.
