1、Designation:F129516Standard Specification forWrought Titanium-6Aluminum-7Niobium Alloy for SurgicalImplant Applications(UNS R56700)1This standard is issued under the fixed designation F1295;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revi
2、sion,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 This specification covers the chemical,mechanical,andmetallurgical requirements for wrought annealed,cold
3、-worked,or hot-worked titanium-6aluminum-7niobium alloy bar,wire,sheet,strip,and plate to be used in the manufacture of surgicalimplants(1-4).21.2 The SI units in this standard are the primary units.Thevalues stated in either primary SI units or secondary inch-pound units are to be regarded separate
4、ly as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with the standard.2.Referenced Documents2.1 ASTM Standards:3E8/E8M Test Methods for Tension T
