     We offer many different alloys for you to choose from.  This page, in particular, is dedicated to giving the specifications for Aluminum Bronze 9D.  The ingot numbers that you find listed in the furnace room pages, such as Aluminum Bronze 9D, 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

Note: The unified numbering system (UNS) is an alloy designation system, widely accepted in North America


Aluminum Bronze 9D      UNS No. C95500     To go back to the home page or to choose other bronze or aluminum alloys.

Major Uses: Nuts, Gears, Bushings, Pickling Equipment, Welding Jaws, Valve parts, Marine Hardware, Electrical Hardware.

The family of aluminum bronze alloy offers high strength and hardness, excellent corrosion resistance, good wearing qualities and good fatigue resistance. The alloys are well suited for service at temperatures up to 750 F The properties of alloys within certain composition ranges can be improved further by heat treatment Keep in mind that low carbon mild steel might typically come in something like 85 brinell and 55 tensile, lets compare it to Aluminum Bronze 9D

The following information was obtained from Casting
Copper Base Alloys, published by the American Foundry
Society.

Mechanical Properties at elevated temperatures

   Alloys C95400 and C95700 were tested at 450F

Limiting Creep Strength

   C95700                      tested to 700F
   C95200 & C95400    tested to 900F
   C95500                      tested to 800F

That is all the information I have regarding testing,
of aluminum bronzes, at elevated temperatures
