ASTM Standard

ASTM F67 — Standard Specification for Unalloyed Titanium, for Surgical Implant Applications (UNS R50250, UNS R50400, UNS R50550, UNS R50700)

ASTM F67 covers the chemical, mechanical, and metallurgical requirements for four grades of unalloyed commercially pure titanium (Grades 1, 2, 3, and 4) used in surgical, dental, and maxillofacial implants.

Scope

Covers the chemical, mechanical, and metallurgical requirements for four grades of unalloyed titanium (Grades 1, 2, 3, and 4) used in the manufacture of surgical implants.

Covered Grades

Grade 1 Grade 2 Grade 4

Covered Product Forms

Strip Sheet Plate Bar Billet Wire

Key Requirements

Unalloyed titanium chemistry with step-wise oxygen limits from Grade 1 (0.18% max) to Grade 4 (0.40% max)
Minimum tensile strength ranging from 240 MPa (Gr1) to 550 MPa (Gr4 annealed)
Equiaxed alpha grain size no coarser than ASTM E112 No. 5
Bend test compliance for flat sheet and strip

Test Methods

ASTM E8 (Tensile)
ASTM E1409 (Inert Gas Fusion)
ASTM E290 (Bend Testing)
ASTM E112 (Grain Size)

Metallurgical Verification & Quality Control

Within ASTM F67, Grade 1 offers the highest ductility for cranial plates and maxillofacial mesh, whereas Grade 4 (and cold-worked Grade 4) delivers the highest strength of unalloyed titanium—making it the global standard for vanadium-free and aluminum-free dental implants.

What to Specify on Your ASTM F67 Purchase Order / RFQ

Standard and grade: ASTM F67 Grade 1, Grade 2, Grade 3, or Grade 4 (and ISO 5832-2 if required)
Condition: annealed or cold-worked (specify target minimum UTS if ordering cold-worked Grade 4 dental bar)
Form, dimensions, and precision tolerance (e.g., h6/h7 ground bar for dental CNC turning or thin sheet for bone plates)
Grain size and ultrasonic inspection requirements
Certification: material test certificate (MTC) with ASTM E112 grain size rating, chemical/gas analysis, and tensile test report

Code Equivalency & Companion Standards

ASTM F67 corresponds to ISO 5832-2. When higher yield strength (>790 MPa) is required for load-bearing orthopedic joints and spine hardware, specify ASTM F136 (Grade 23 Ti-6Al-4V ELI).
