ASTM B936-04

Standard Specification for Copper-Chrome-Iron-Titanium Alloy Plate, Sheet, Strip and Rolled Bar

SCOPE
1.1 This specification establishes the requirements for Copper Alloy UNS No. C18080 for plate, sheet, strip, and rolled bar alloy.
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—Coppeer 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, which you may attend.
1.2 Unites—Values stated in inch-pound units are to be regarded as the standard. Values given in parentheses are mathematical conversions to SI unites, which are provided for information only.
