ASTM F67 is the material standard that specifies the requirements for unalloyed titanium used in the manufacture of surgical implants. ASTM F67 covers commercially pure (CP) titanium, including Gr1, Gr2, Gr3 and Gr4, which is valued for its exceptional corrosion resistance, biocompatibility, and formability, but offers lower strength. It is commonly used for non-load-bearing or low-load medical implants.

Chemical Composition And Mechanical Properties (For Annealed Titanium Bars)

Property	Grade 1	Grade 2	Grade 3	Grade 4
Iron Content (max)	0.20%	0.30%	0.30%	0.30%
Oxygen Content (max)	0.18%	0.25%	0.35%	0.40%
Tensile Strength	≥ 240 MPa	≥ 345 MPa	≥ 345 MPa	≥ 550 MPa
Yield Strength (0.2% Offset)	≥ 170 MPa	≥ 275 MPa	≥ 275 MPa	≥ 485 MPa
Elongation	≥ 24%	≥ 20%	≥ 18%	≥ 15%
Area of Reduction	≥ 30%	≥ 30%	≥ 30%	≥ 25%
Modulus of Elasticity	~105 GPa	~105 GPa		~105 GPa
Key Characteristics	Highest ductility, lowest strength. Excellent formability.	The standard, balanced grade. Excellent combination of strength and ductility.	Medium strength. Less common than Grade 2 or 4.	The strongest unalloyed grade. Still maintains good ductility.

Note: The modulus of elasticity for pure titanium is about half that of stainless steel or cobalt-chromium alloys, and significantly lower than Ti6Al4V, which reduces stress shielding.

Medical Applications

Due to its lower strength but high biocompatibility, ASTM F67 pure titanium bars are used in specific types of implants.

Dental Implants: Grade 4 ASTM F67 pure titanium bars are very commonly used for the main body (fixture) of dental implants, where its high strength within the CP family is sufficient for the masticatory loads.
Cranio-Maxillofacial (CMF) Implants: Plates, meshes, and screws for reconstructive surgery of the skull and face. The ability to contour the material is a major advantage.
Pacemaker Cases and Implantable Device Housings: Its excellent corrosion resistance protects sensitive electronics.
Orthopedic Applications: Bone screws (particularly in non-load-critical areas), surgical mesh, and wire.
Ear, Nose, and Throat (ENT) Implants: Such as ossicular replacement prostheses in the middle ear.

Conclusion

ASTM F67 pure titanium bars are the material of choice when the primary requirements are maximum biocompatibility, superior corrosion resistance, and excellent formability, and where the mechanical loads are not extreme. Grade 2 offers a great balance for many applications, while Grade 4 provides the highest strength available in the commercially pure titanium family, making it suitable for critical applications like dental implants.
