2 copper, 55 cents for radiators and 85 cents for red brass," says Peter.

Southern Centrifugal melts 30 different alloys--aluminum bronze, red brass, manganese bronze and monels, as well as high-leaded, proprietary alloys--in its manufacturing process.

Another type of brass is "red brass," which is less than 15% zinc.

* Located on the outside wall of the house, frostproof sill cocks are made of heavy red brass and look and work like any ordinary faucet.

Red brass has moved around 55 cents, and yellow brass has been a dime to 15 cents less.

If up to 8pc is zinc, the alloy produces a copper colour while between 8pc and 14pc it becomes a reddishgold, known as "Tombac" or "red brass".

MetalTek was melting 30 different alloys - red brass, manganese bronze, monels, as well as high leaded, proprietary alloys - in their manufacturing process.

* EnviroBrass I and II (C89510 and C89520) were developed to replace C83600 leaded red brass and C84400 semi-red brass.

Globe Valve, Delphi, Indiana, casts a red brass alloy (6% lead), CDA848, using green sand molds and a low-lead yellow brass alloy (1.2% lead), CDA857-10 B2, using a low-pressure permanent mold process.

The creation of this red brass mural overcame several production obstacles with the right mix of talent and creativity.
