Standard Classification for Temper Designations for Copper ...

1 Designation: B 601 02 Standard Classification forTemper 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 oforiginal 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 Standard has been approved for use by agencies of the Department of Scope * This is a classification of Temper Designations for copperand Copper alloys wrought and cast.

2 The Temper designationsare classified by the process or processes used in manufactur-ing the product involved and its resulting qualities. It is not aspecification of Copper and Copper alloy The property requirements for the tempers are given inthe applicable product Referenced Standards:B 846 Terminology for Copper and Copper Alloys23. For terminology related to Copper and Copper alloys,refer to Terminology B Significance and This classification establishes an alpha-numeric code of the tempers of Copper and Copper The alphanumeric code is used to designate prod-uct tempers in specifications and published The letters in the code identify the type of processused to produce the product Temper .

3 For example, H indi-cates a Temper resulting from cold These letters are frequently the same as those used in tempersystems of other metal Classification of Tempers, O Tempers produced by annealingto meet mechanical property Tempers, OS Tempers produced by anneal-ing to meet Standard or special grain size Tempers, M Tempers produced in theproduct by the primary manufacturing operations of castingand hot working and controlled by the methods employed inthe Tempers, H Tempers produced by con-trolled amounts of cold (Drawn)

4 , Stress-Relieved Tempers, HR Tempers produced by controlled amounts of cold work fol-lowed by stress Tempers, HT Tempers pro-duced by controlled amounts of cold work followed by athermal treatment to produce order Tempers, T Tempers that are based onheat treatments followed by rapid Tempers, TQ Tempers producedby quench-hardening Heat-Treated Temper , TB Tempers pro-duced by solution heat-treating precipitation hardenable orspinodal hardenable Heat-Treated and Cold-Worked Tempers,TD Tempers produced by controlled amounts of cold work ofsolution heat-treated precipitation hardenable or spinodal hard-enable Heat-Treated Temper , TF Tempersproduced by precipitation heat treatment of precipitation-hardenable Heat Treated Temper .

5 TX Tempers pro-duced by spinodal heat treatment of spinodal and Precipitation Heat-Treated Tem-pers, TH Tempers produced in alloys that have been solutionheat treated, cold worked, and precipitation heat and spinodal Heat-Treated Tempers,TS Tempers produced in alloys that have been solution heattreated, cold worked, and spinodal heat Tempers, TM Tempers of heat-treated materials as supplied by the mill resulting fromcombinations of cold work and precipitation heat treatment orspinodal heat Heat-Treated or spinodal Heat-Treated1 This classification is under the jurisdiction of ASTM Committee B05 onCopper and Copper Alloys and is the direct responsibility of Subcommittee Editorial and edition approved Oct.
