Designation:B84611aStandard Terminology forCopper and Copper Alloys1This standard is issued under the fixed designation B846;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()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 The terms defined in this terminology standard areapplicable to copper and copper alloy products specifications,test methods,practices,and other documents within the juris-diction of Committee B05 on Copper and Copper Alloys.2.Referenced Documents2.1 ASTM Standards:2B153 Test Method for Expansion(Pin Test)of Copper andCopper-Alloy Pipe and TubingB170 Specification for Oxygen-Free Electrolytic CopperRefinery ShapesB379 Specification for Phosphorized CoppersRefineryShapesE8 Test Methods for Tension Testing of Metallic MaterialsE10 Test Method for Brinell Hardness of Metallic MaterialsE18 Test Methods for Rockwell Hardness of Metallic Ma-terialsE23 Test Methods for Notched Bar Impact Testing of Me-tallic MaterialsE112 Test Methods for Determining Average Grain Size3.Significance and Use3.1 This terminology is not intended to apply to anystandard,test method,practice,or other document not withinthe jurisdiction of Committee B05 on Copper and CopperAlloys.4.Terminologyacid dipsee dip solution.acid dipped-dry rolled finishsee finish,acid dipped-dryrolled.Admiraltyan alloy containing nominally 71%copper:1%tin and 28%zinc,originally developed by the BritishAdmiralty and generally available in tube,flat products,andwire.Its principal use is in heat exchanger and condensertubes.An inhibitor may be added to increase the resistance todezincification.Admiralty,inhibited(arsenical,antimonialorphosphorized)admiralty modified by the addition ofsmall amounts of arsenic,antimony or phosphorus to inhibitdezincification.(Copper Alloy Nos.C44300,C44400,C44500)air stainsee stain,air.alphathe name of a phase or of a certain range of copperalloys which contain one or more alloying elements dis-solved in copper,the phase being a homogeneous solidsolution.alpha beta brassa series of copper-zinc alloys containingapproximately 55 to 63%copper and the remainder mostly,if not all,zinc and composed of crystals or grains of both thealpha and the beta phases.aluminum brassa copper alloy containing nominally77.5%copper,2%aluminum and 20.5%zinc with anarsenical inhibitor,available in tube form.Its principal use isin heat exchanger and condenser tubes.(Copper Alloy No.C68700)aluminum bronzecopper alloys with aluminum as theprincipal alloying element,normally in the range of 3 to11%with or without the additions of other elements.(Copper Alloy Nos.C60800 64699 incl.)anneal(annealing)a thermal treatment to change the prop-erties or grain structure of the product.When applied to acold-worked product having a single phase:to producesoftening by recrystallization or recrystallization and graingrowth,with the accompanying changes in properties.Whenapplied to a product having two or more phases:to producesoftening by changes in the phase relationship that mayinclude recrystallization and grain growth.annealability of copper rodthe ease with which a materialwill soften after cold work and subsequent thermal treat-ments;this property is affected primarily by the purity of themetal since all other variables are kept constant.1This terminology is under the jurisdiction ofASTM Committee B05 on Copperand Copper Alloys and is the direct responsibility of Subcommittee B05.93 onTerminology.Current edition approved June 1,2011.Published July 2011.Originally approvedin 1993.Last previous edition approved in 2011 as B846 11.DOI:10.1520/B0846-11A.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 annular ringsee circular ring.arbora cylindrical core around which metal is wound toobtain a desired inside diameter of the wound coil or roll.arc weldinga group of welding processes wherein coales-cence is produced by heating with an arc or arcs,with orwithout the application of pressure,and with or without theuse of filler metal.architectural bronzean alloy containing nominally 57%copper,3%lead,and 40%zinc,generally available inextruded or drawn shapes and rod;used for architectural trimand for some mechanical applications.The alloy is nottechnically a bronze,but because of long usage,the term“Architectural Bronze”has been used.(Copper Alloy No.C38500)area reductionthe decrease in cross-section of a product byrolling or drawing,which is a measure of the temper of themetal in the cold worked condi
