Is ASTM F-136 titanium implant grade?
Yes, ASTM F136 titanium is commonly referred to as an implant-grade titanium alloy. The ASTM F136 specification specifically defines the requirements for a type of titanium alloy, namely titanium-6 aluminum-4 vanadium (Ti-6Al-4V) alloy with extra low interstitial (ELI) levels, which makes it highly suitable for medical implant applications.
The ELI designation indicates that the titanium alloy has been refined to have even lower levels of impurities, particularly interstitial elements like oxygen and nitrogen. These impurities can affect the biocompatibility and mechanical properties of the material. By having such low interstitial content, ASTM F136 titanium exhibits exceptional biocompatibility, corrosion resistance, and mechanical strength, making it an excellent choice for various types of medical implants, including orthopedic, dental, spinal, and other implants.
Because of its favorable properties and compliance with strict standards for medical applications, ASTM F136 titanium is widely recognized and used as an implant-grade material by medical professionals and manufacturers in the field of medical devices and implants.
