We offer many different alloys for you to choose from. This page, in particular, is dedicated to giving the specifications for #421 Manganese bronze. The ingot numbers that you find listed in the furnace room pages, such as #421 Manganese bronze., 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, that will
require 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
Note: The unified numbering system
(UNS) is an alloy designation system, widely accepted in North America.
