Standard Classification ofCOPPERS 1

This standard is issued under the fixed designation B 224; the number immediately following the designation indicates the year ooriginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapprovaA superscript epsilon (,l indicates an editorial change since the last revision or reapproval. This classification has been approved for use by agencies of the Department of Defense and for listing in the DoD Index oSpecificat ions and Standards.,I NOTE Reference to "lake copper" has been deleted from Table A I in October 1982 because such terminology is no longer used

1. Scope1.1 This is a classification of the various typesof copper currently available in refinery shapesand wrought products in commercial quantities.

It is not a specification for the various types ofcopper.

A3. DEFINmONS OF REFINERY SHAPESA3.l billet-refmery shape llsed for piercing orextrusion into tubular products or for extrusion intorods, bars, and shapes. Circular in cross section,usually 3 to 16 in. (76 to 406 mm) in diameter,normally ranging in weight from 100 to 4200 lb (45to 1905 kg). .A3.2 cake-refinery shape used for rolling intoplate, sheet, strip, or shape. Rectangular in crosssection and of various; sizes, normally ranging inweight from 140 to 62 000 lb (63 to 28 200 kg).A3.3. cathode-unmelted, electrodeposited, andsomewhat rough flat plate normally used for melting.The customary size is about 3 ft (0.914 m) square,

up to about 300 lb (136 kg), and may have hangingloops attached. Cathodes may also be cut to smallerdimensions.A3.4 ingot and ingot a r ~ r e f m e r y shapes used forremelting (not fabrication). Ingots normally range inweight from 20 to 35.1b (9 to 16 kg) and ingot barsfrom 50 to 70 lb (23 to 32 kg). Both are usuallynptcQ.ed to facilitate breaking into smaller pieces.. A3.5 wire bar-refmery shape used for rolling intorod or flit product fot subsequent processing intowire, strip, or shape. Approximately 3% to 5 in.
