COPPER ALLOY DATA SHEET

C23000

Red Brass C23000 is generally regarded as the most durable of all metals for commercial water pipe in the practical price range. Nominally composed of 85% copper and 15% zinc, this alloy is excellent for its resistance to dezincification and season cracking for which the high copper brasses are known. It has moderate strength and good retention of spring properties. Resistance to pitting is also particularly good.

Hot and Cold Working: C23000 has good hot workability and excellent cold workability. It is excellent for drawing, spinning, stamping, blanking, or any drastic cold working operations. The metal for this type of operation is furnished in an annealed condition and is classified by grain size, making it easily measurable by both the producer and the consumer, and giving a direct relation to overall mechanical properties.

Joining: Joining by soldering and brazing is excellent. Good joints can be obtained by oxyacetylene and gas shielded arc welding. Rod, bar and wire may be resistance flash butt-welded.

Applications: C23000 is frequently specified for underground service lines assembled with threaded connections because it offers greatest corrosion resistance to all types of potable waters. Specific applications include costume jewelry, fire hose couplings, and zippers. Because of its availability in several forms, and because of its rich inherent color, it also has become extremely popular as an outdoor metal and has found for itself a very important place in modern architecture. An endless variety of shapes can be obtained by shape-drawing, brake-forming and shape rolling processes. For tube, typical uses are flexible metal hose, electrical conduit, pump liners and paper rolls.

Applicable Specifications: When so specified, C23000 will be manufactured to the latest revision of the following specifications: for rod and wire, ASTM Specification B134, and for tube, ASTM Specification B135.

Standard Forms Available: Rod, bar, wire and tube. For other forms, please consult Ansonia Copper & Brass, Inc.
