Standard Specification for Wrought Titanium-6Aluminum-7Niobium Alloy for Surgical Implant Applications (UNS R56700)
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the chemical, mechanical, and metallurgical requirements for wrought annealed, cold worked, or hot rolled titanium-6aluminum-7niobium alloy (UNS R56700) bar and wire to be used in the manufacture of surgical implants. Titanium mill products covered in this specification shall be formed with the conventional forging and rolling equipment found in primary ferrous and nonferrous plants, and may be furnished as descaled or pickled, sandblasted, chemically milled, ground, machined, peeled, polished, or cold drawn. The alloy shall be multiple melted in arc furnaces (including furnaces such as plasma arc and electron beam) of a type conventionally used for reactive metals. Heat analysis shall conform to the chemical composition requirements prescribed for aluminum, niobium, tantalum, iron, oxygen, carbon, nitrogen, hydrogen, and titanium. The material shall conform to the specified requirements for mechanical properties such as ultimate tensile strength, yield strength, and elongation. A minimum of two tension tests from each lot shall be performed. Special requirements for the microstructure are detailed as well.
Scope
1.1 This specification covers the chemical, mechanical, and metallurgical requirements for wrought annealed, cold-worked, or hot-worked titanium-6aluminum-7niobium alloy bar, wire, sheet, strip, and plate to be used in the manufacture of surgical implants (1-4).2
1.2 The SI units in this standard are the primary units. The values stated in either primary SI units or secondary inch-pound units are to be regarded separately as standard. The values 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.
