Standard Classification for

Temper Designations for Copper and Copper Alloys— Wrought and Cast1
This standard is issued under the fixed designation B 601; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.

1. Scope * 1.1 This is a classification of temper designations for copper and copper alloys—wrought and cast. The temper designations are classified by the process or processes used in manufacturing the product involved and itsresulting qualities. It is not a specification of copper and copper alloy products. 1.2 The property requirements for the tempers are given in the applicable product specification. 2. Referenced Documents 2.1 ASTM Standards: B 846 Terminology for Copper and Copper Alloys2 3. Terminology 3.1 For terminology related to copper and copper alloys, refer to Terminology B 846. 4. Significance and Use 4.1Significance—This classification establishes an alphanumeric code of the tempers of copper and copper alloy products. 4.2 Use—The alphanumeric code is used to designate product tempers in specifications and published data. 4.2.1 The letters in the code identify the type of process used to produce the product temper. For example, “H” indicates a temper resulting from cold working.
NOTE 1—These lettersare frequently the same as those used in temper systems of other metal products.

5. Classification of Tempers 5.1 Annealed Tempers, O—Tempers produced by annealing to meet mechanical property requirements. 5.2 Annealed Tempers, OS—Tempers produced by annealing to meet standard or special grain size requirements.
