What this plate is for
Surgical implants need strength. The plate holds bone while it heals. The patient moves. The implant cycles. It can't fail.
Ti‑6Al‑4V ELI medical plate for surgical implants is the standard for load-bearing orthopaedics. ELI stands for Extra Low Interstitial. Lower oxygen. Lower iron. Tougher than regular Grade 5.
Trauma plates. Locking plates. Reconstruction plates. Spine plates. Anywhere a bone needs fixation and the implant sees stress.
Why ELI over regular Grade 5
Regular Grade 5 (Ti-6Al-4V) is strong. Tensile 895 MPa. But it has higher oxygen. Higher iron. Slightly lower toughness.
ELI drops oxygen from 0.20% max to 0.13% max. Iron from 0.30% max to 0.25% max.
What does that mean for implants? Better fracture toughness. Better fatigue life. Better ductility. For a plate that goes into an active patient, these matter.
Ti‑6Al‑4V ELI medical plate for surgical implants gives you the strength of Grade 5 with a higher safety margin. ASTM F136 is the medical spec. ISO 5832-3 is the international version. Same material.

Common plate applications

| Small fragment (hand, foot) | 0.8 – 1.5 | 5 – 8 | Locking or non-locking |
| Medium (forearm, ankle) | 1.5 – 2.5 | 8 – 12 | High stress |
| Large (femur, tibia) | 2.5 – 4.0 | 12 – 18 | Load bearing |
| Locking plates | 3.0 – 5.0 | 10 – 20 | Threaded holes |
| Spine (anterior cervical) | 1.5 – 2.5 | 10 – 18 | Precision holes |
| Mandibular reconstruction | 1.5 – 2.5 | 6 – 10 | Load sharing |
Each plate starts as Ti‑6Al‑4V ELI medical plate for surgical implants stock. Laser cut. CNC drilled. Deburred. Passivated. Finished.
Where these plates go
- A trauma surgeon fixes a fractured femur. Big plate. 4.0mm thick. Locking screws. Patient weight-bearing in weeks.
- Ankle fracture. Fibula plate. 2.0mm thick. Non-locking or locking. Patient walks with a boot.
- Forearm fracture. Radius or ulna plate. 1.5mm to 2.0mm. Thin. Strong.
- Spine fusion. Anterior cervical plate. Small screws. Precise hole spacing. 1.5mm thick.
- Reconstruction after tumor resection. Custom plate. Patient-specific contour. Long spans.
- Veterinary orthopaedics. Dog femur. Cat tibia. Same material. Smaller sizes.
- Every one of these plates uses Ti‑6Al‑4V ELI medical plate for surgical implants because regular Grade 5 isn't tough enough for long-term cyclic loading.
ELI vs Grade 4 pure titanium
| Property | ELI (Grade 23) | Grade 4 CP |
| Tensile | 860 MPa | 550 MPa |
| Strength/weight | Very high | Medium |
| Ductility | Good | Better |
| Best for | Load-bearing trauma | Cranial, maxillofacial |
Grade 4 is pure titanium. Softer. More ductile. Used for cranial plates and low-stress applications.
ELI is stronger. Used for weight-bearing bones. Femur. Tibia. Spine. Forearm.
For Ti‑6Al‑4V ELI medical plate for surgical implants, the high strength allows thinner plates. Less material in the patient. Better soft tissue coverage.
Locking vs non-locking plates
Locking plates have threaded screw holes. The screw locks into the plate. Creates a fixed-angle construct. Better for weak bone. Osteoporotic patients. Comminuted fractures.
Non-locking plates use standard screws. Compression across the fracture.
Ti‑6Al‑4V ELI medical plate for surgical implants can be made either way. Locking plates need thicker material. More threads. Tighter tolerances.
Most trauma plates today are locking.
Surface finish for implants
Implants need clean, biocompatible surfaces.
Polished. Ra ≤ 0.2μm. Smooth. Bright. Resists bacterial adhesion.
Anodized. Color finish. Blue, gold, purple, green, pink. Voltage controls color. Anodizing thickens the natural oxide layer. Improves wear resistance. Helps identify plate type and size.
Sandblasted. Matte finish. Bone-contact surface. Promotes bone growth. Increased surface area.
For Ti‑6Al‑4V ELI medical plate for surgical implants, anodized is common for trauma plates. Color coding by thickness. Blue for 1.5mm. Gold for 2.0mm. Purple for 2.5mm. Green for 3.0mm.
Traceability and certification
Surgical implants are regulated. Class II or III. Full traceability from melt to finished plate.
Every Ti‑6Al‑4V ELI medical plate for surgical implants blank comes with:

FAQ
Q: ELI or regular Grade 5 for implants?
A: ELI. ASTM F136 requires ELI chemistry. Regular Grade 5 (ASTM B348) is not approved for surgical implants. Use F136 material.
Q: What certifications come with the plate stock?
A: ASTM F136 or ISO 5832-3 cert. MTR with heat number. Mechanicals. EN 10204 3.1. 3.2 available.
Q: Lead time for ELI plate stock?
A: Stock thicknesses (1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm) ship in 7-10 days with paperwork. Non-stock sizes take 3-5 weeks.
Q: Cut to plate shape?
A: Yes. Send your DXF or DWG. We laser cut. Deburr. Passivate. Pack. Minimum order applies.
Q: What about anodizing?
A: We offer anodizing. Blue, gold, purple, green, pink. Specify color. Anodizing adds 3-5 days.
Q: Can you supply patient-specific plates?
A: Yes. Send the 3D model or STL file. We work from your design. Many trauma and reconstruction cases use custom plates.
