ASTM B592 - 11 standard specification for copper-zinc-aluminum-cobalt alloy, copper-zinc-tin-iron alloy plate, sheet, strip, and rolled bar


Source: ASTM International

This specification covers the requirements for plates, sheets, strips, and rolled bars of copper-zinc-aluminum-cobalt (Copper Alloy UNS No. C68800) and copper-zinc-tin-iron (Copper Alloy UNS No. C66300) alloys. The material for manufacture shall be a cast bar, cake, slab or so forth of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in tempers H (rolled), and O (annealed to temper). Products shall be tested to examine their conformance to dimensional (mass, thickness, length, straightness, and edge), mechanical (tensile strength, and Rockwell hardness), electrical (resistivity and equivalent conductivity), chemical composition, and grain size requirements.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers the requirements for plate, sheet, strip, and rolled bar in alloys C66300 and C68800.

Note 1—Since alloy C68800 is frequently used in a variety of applications where yield strength and stress-corrosion resistance may be critical, it is recommended that drawings or samples of the part to be fabricated and details of application be submitted for use in establishing temper and treatment of material.

Note 2—Alloy C66300 is covered by a patent. Interested parties are invited to submit information regarding the identification of an alternative(s) to this patented item to the ASTM International Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
