ASTM F67 Grade 4 Medical Titanium Bar UNS R50700 CP‑Ti Rod

Published by Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd on 2026-10-25

1. Core Parameters

• Material: Commercially Pure Titanium Grade 4 (CP‑Ti), UNS R50700
• Product Forms: Round, Square, Hexagonal, Flat, custom profiles
• Condition: Annealed, Stress‑Relieved or as‑specified
• Dimension: Custom diameter; fixed / random cut‑to‑length
• Target Industries: Medical implant, surgical device, dental component
• Lead‑time: Standard stock 7‑14 working days; custom forging 20‑35 working days

2. Product Definition

Grade4 titanium bar under ASTM F67 is unalloyed commercially pure titanium for biomedical manufacturing.

• By forming process: Hot‑forged bar, hot‑rolled bar, cold‑drawn precision bar
• By structural shape: Round bar, square bar, hexagonal bar, flat bar, custom blanks

3. Material Advantage: Material‑Medium‑Corrosion‑Cleanliness

Grade4 CP‑Ti delivers the highest tensile strength among unalloyed titanium grades while keeping excellent biocompatibility.

• Body fluid medium: Resists corrosion in human body fluid, saline and blood environment; no toxic ion precipitation for long‑term implantation.
• Surface cleanliness: Medical‑grade bars remove oil, particle and contamination via ultrasonic cleaning; controlled surface roughness for implant machining; free of heavy‑metal residual.
• Corrosion performance: Good resistance against chloride‑rich media; avoids pitting corrosion inside human tissue.

4. Technical Standards

• Main medical standard: ASTM F67 (surgical implant unalloyed titanium)
• Equivalent international: ISO 5832‑2
• General material standard: ASTM B348
• Traceability certificate: EN 10204 3.1 MTC; batch‑lot traceability for medical‑related order.

5. Full Manufacturing Workflow: From Drawing To Finished Goods

1. Raw material: High‑purity titanium sponge incoming inspection.
2. VAR vacuum arc remelting: Multiple remelting to stabilize chemical composition and control interstitial elements (O, N, H).
3. Hot forging / hot rolling: Refine grain structure, eliminate casting defects.
4. Heat treatment: Annealing or stress‑relief treatment for stable mechanical performance.
5. Peeling / turning: Remove surface oxidation layer.
6. Pickling & precision grinding: Reach required dimension tolerance and surface finish.
7. Ultrasonic cleaning for medical cleanliness requirement.
8. Final inspection & labeling, packing for export shipment.

6. Key Component Performance

• Weldability: Good weld performance; no brittle phase when properly welded under protective gas.
• Non‑destructive test: Ultrasonic flaw detection for internal defects; eddy‑current test for surface crack inspection.
• Mechanical test: Tensile strength, yield strength, elongation test per ASTM F67 requirements.

7. Application Industry — Medium‑Equipment‑Process

• Medical implant industry
  • Medium: Human body fluid, saline environment
  • Equipment & parts: Bone fixation screw, bone plate, dental implant blank, surgical instrument substrate
  • Process: CNC machining, precision grinding for final medical devices
• Special‑purpose industrial field
  • Medium: Chloride‑containing corrosion medium
  • Equipment: Marine fastener, chemical precision shaft
  • Process: Forging, turning, cutting processing
