(Classification)Standard Classification for Temper Designations for Copper and Copper Alloys—Wrought and Cast
Standard Classification for Temper Designations for Copper and Copper Alloys—Wrought and Cast
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 its resulting 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.

Wrought and Cast
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. A
superscript 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.
