Standard Specification for Copper-Chromium-Iron-Titanium Alloy Plate, Sheet, Strip and Rolled Bar
ABSTRACT
This specification establishes the requirements for plates, sheets, strips, and rolled bars of copper-chromium-iron-titanium alloys with Copper Alloy UNS No. C18080. 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 subsequent annealing to produce finished products that have a uniform wrought structure and meet the specified temper properties. Products shall be available in the mill hardened temper (TM). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, thickness, width, length, straightness, and edge), mechanical (tensile strength and Rockwell hardness), electrical (resistivity and equivalent conductivity), and chemical composition requirements.
SCOPE
1.1 This specification covers the requirements for Copper Alloy UNS No. C18080 for plate, sheet, strip, and rolled bar.
Note 1: Since Copper Alloy UNS No. C18080 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: Copper Alloy UNS No. C18080 is covered by a patent. Interested parties are invited to submit information regarding the identification of an alternative(s) to this patented item to ASTM International headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.
1.2 Units—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.
1.3 The following safety hazard caveat pertains only to the test method(s) described in this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
