Overview
ASTM F1713-08(2021)e1 is a widely recognized standard developed by ASTM International for wrought titanium-13niobium-13zirconium alloy (UNS R58130) used in surgical implant applications. This specification defines the essential chemical, mechanical, and metallurgical requirements for bars and wires produced from this titanium alloy, which is notable for its excellent corrosion resistance, high strength, and biocompatibility. The specified alloy is intended primarily for the manufacture of devices requiring reliable, long-term performance in the human body, such as orthopedic implants.
Key Topics
- Material Composition: The standard details the precise chemical composition of titanium-13niobium-13zirconium alloy, including allowable limits for critical elements like niobium, zirconium, oxygen, nitrogen, carbon, and hydrogen.
- Product Forms: Bars (rounds or flats) and wires are covered, intended for further manufacturing into surgical devices.
- Material Conditions: The specification allows for material to be supplied in unannealed, solution-treated, or capability-aged states, giving manufacturers flexibility based on required product properties.
- Mechanical Properties: Included are minimum requirements for tensile strength, yield strength, elongation, and reduction of area to ensure the alloy meets performance expectations for surgical applications.
- Surface Finish: Mill products must be provided with a finish suitable for surgical implant manufacture, such as descaled, pickled, abrasive blasted, chemically milled, ground, machined, peeled, or polished, depending on purchaser needs.
- Testing and Quality: The standard references established test methods for ensuring material conformity, including tension testing and chemical analysis. A quality program such as ISO 9001 is required to ensure ongoing compliance.
Applications
- Surgical Implants: Designed specifically for use in manufacturing orthopedic implants, such as joint replacements, bone plates, screws, and other medical devices that require high strength, ductility, and corrosion resistance.
- Biocompatibility: The alloy’s composition and mechanical properties have been optimized through research and clinical experience to ensure improved biological response and long-term compatibility with human tissues.
- Customization: The standard enables suppliers to provide alloy bars or wires with requested properties or surface finishes to suit particular implant design requirements.
