What this plate is for
Skull fractures. Facial trauma. Tumor resection. Congenital deformities.
Craniofacial reconstruction titanium plate ASTM F67 is what neurosurgeons and craniofacial surgeons use to rebuild the skull and face. The bone is thin here. The contours are complex. Cosmetic outcome matters.
ASTM F67 means pure titanium. No aluminum. No vanadium. Just titanium. Biocompatible. MRI compatible. Bone grows right to it.
Why ASTM F67 for craniofacial, not F136
ASTM F136 is Ti-6Al-4V ELI. Stronger. Used for load-bearing bones like femur and tibia.
But the skull and face don't see high loads. A cranial plate holds a bone flap in place. It doesn't carry body weight.
Craniofacial reconstruction titanium plate ASTM F67 uses pure titanium. Grade 2 or Grade 4. Lower strength than F136. But more ductile. Easier to cut. Easier to bend during surgery. And no aluminum or vanadium - some surgeons prefer this for the head.
For thin plates under 1.0mm, pure titanium bends without cracking. F136 is too stiff.
Which grade for craniofacial
| Grade | Tensile | Best for |
| Grade 2 | 345 MPa | Thin plates. Mesh. Contoured shapes. Easier to bend. |
| Grade 4 | 550 MPa | Thicker plates. Load-sharing applications. More strength. |
Grade 2 is softer. More ductile. Used for cranial mesh, orbital floor plates, and thin contour plates. The surgeon can cut and bend it with tools on the table.
Grade 4 is stronger. Used for mandibular reconstruction plates and thicker cranial plates. Still bendable but takes more force.
For craniofacial reconstruction titanium plate ASTM F67, Grade 2 is more common. Grade 4 for larger defects or load-bearing areas like the mandible.

Where these plates go
- Craniotomy. The surgeon removes a bone flap to access the brain. After surgery, the flap goes back. Craniofacial reconstruction titanium plate ASTM F67 holds it in place. Small plates. 3 to 6 holes. Screws into the skull.
- Cranial mesh. Large skull defects. Tumor resection. Trauma. Mesh is cut to shape. Bent to match the skull curvature. Screwed down.
- Orbital floor. Eye socket fractures. Thin plates. 0.4mm to 0.6mm. Contoured to fit under the eye.
- Midface trauma. Zygomatic. Maxillary. Le Fort fractures. Plates along the facial bones.
- Mandibular reconstruction. Jaw reconstruction after tumor removal. Thicker plates. 1.5mm to 2.0mm. Load-bearing.
- Pediatric craniofacial. Growing skulls need special considerations. Pure titanium expands with growth better than stiffer alloys.
- Each plate starts as craniofacial reconstruction titanium plate ASTM F67 stock. Laser cut. Polished. Anodized. Sterilized.
Why pure titanium for the head
Three reasons.
- First, MRI compatibility. Patients with brain tumors need follow-up MRIs. Pure titanium is non-ferromagnetic. Minimal artifact on MRI. F136 (Ti-6Al-4V) also works, but pure titanium is even cleaner on imaging.
- Second, ductility. The skull is curved. Every patient is different. The surgeon bends the plate to fit. Pure titanium bends easier than alloy.
- Third, no aluminum or vanadium. Some surgeons prefer to avoid these elements in the head. Aluminum concerns are theoretical. But the preference exists.
For craniofacial reconstruction titanium plate ASTM F67, pure titanium is the traditional choice. Proven for decades.
Surface finish
Craniofacial plates touch soft tissue. Scalp. Dura. Facial muscles. Surface finish matters.
Polished. Ra ≤ 0.2μm. Smooth. Bright. Minimal tissue irritation.
Anodized. Color finish. Blue, gold, purple. Anodizing thickens the oxide layer. Helps identify plate size and type in surgery. Blue for 0.6mm. Gold for 1.0mm.
Sandblasted. Matte finish. Promotes bone growth. Used for bone-contact surfaces.
For craniofacial reconstruction titanium plate ASTM F67, anodized is very common. Color coding helps surgeons grab the right plate quickly.
Mesh vs solid plates
- Mesh. Holes everywhere. Used for large cranial defects. Bone grows through the holes. Screws placed anywhere. Lightweight. Conformable.
- Solid plates. Standard bone plates. Holes only where screws go. Used for fracture fixation and craniotomy closure.
Both available in craniofacial reconstruction titanium plate ASTM F67. Same material. Same ASTM F67.
Traceability and certification
Medical implants need full traceability. Heat number. Mill test report. Chemistry. Mechanicals.
Every craniofacial reconstruction titanium plate ASTM F67 blank comes with:
- ASTM F67 certificate. Mill test report with heat number. Chemical analysis. Tensile and yield results. Surface finish report.

- For OEM plate manufacturers, we supply stock plates or cut-to-shape blanks.
Fabrication into finished plates
- Laser cut. Clean edge. Minimal heat-affected zone.
- CNC drilling. Hole position tolerance ±0.05mm.
- Deburr. All edges smooth. No sharp corners.

- Final clean. Ultrasonic. Packaged for clean room.
For craniofacial reconstruction titanium plate ASTM F67, we can supply finished plates to your drawing. Many OEMs take this option. Send your DXF or DWG.
FAQ
Q: Grade 2 or Grade 4 for cranial plates?
A: Grade 2 for most cranial. The skull doesn't bear weight. Grade 2 is easier to bend. Grade 4 for mandible or load-sharing applications.
Q: Why not use Grade 23 ELI for craniofacial?
A: Grade 23 ELI is stronger but stiffer. Harder to contour during surgery. For thin plates under 1.0mm, Grade 2 bends without cracking. F136 may crack.
Q: Can I get custom mesh shapes?
A: Yes. Send your 3D model or DXF. We laser cut mesh to your defect shape.
Q: What certifications come with the plate stock?
A: ASTM F67 cert. MTR with heat number. Mechanicals. EN 10204 3.1. 3.2 available.
Q: Lead time for craniofacial plates?
A: Stock thicknesses (0.5mm, 0.6mm, 0.8mm, 1.0mm) ship in 7-10 days with paperwork. Non-stock sizes take 3-5 weeks.
