4. Mechanical & Corrosion Performance
-
Tensile Strength: ≥860 MPa
-
Yield Strength: ≥795 MPa
-
Elongation: ≥15%
-
Biocompatibility: Low interstitial element content, non‑toxic, no rejection risk for human tissue contact.
-
Corrosion Resistance: Excellent corrosion resistance inside human body fluid environment, stable long‑term implant service performance.
-
Processing Feature: Good machinability for turning, milling to produce bone screw and implant parts; strict whole‑process anti‑contamination management for medical‑grade production.
5. Full Size Range
-
Diameter: 4‑100 mm, tolerance h6 / h7 / h8 optional
-
Length: 1000‑3000 mm, custom fixed‑length cutting per drawing
-
Form: Round bar; special‑section bar can be customized for medical component blanks
-
Custom options: Higher precision tolerance, peeling processing, end‑face deburring.
6. Surface Treatment Options
-
Pickling surface: Remove hot‑working oxide layer, for subsequent full machining blank.
-
Polished surface: Ultra‑smooth surface, reduce surface impurity residue for medical implant blanks.
-
Peeling treatment: Completely remove surface contaminated layer, mandatory for high‑end medical implant raw material.
-
Ultrasonic degreasing cleaning: Eliminate processing oil residue before delivery.

Gr23 ELI is specially developed for human implant field. Do not use ordinary industrial Gr5 titanium bar to produce surgical implant components.
8. Strict Quality Control & Test Items
-
Vacuum consumable remelting raw ingot inspection, strict interstitial‑element content control.
-
Whole‑process anti‑iron‑contamination production management for medical‑grade material.
-
Dimension inspection: Diameter tolerance, straightness and length measurement.
-
Mechanical performance test including tensile and elongation index for medical standard.
-
NDT: Ultrasonic UT inspection for internal inclusion and crack defects.
-
Surface inspection: No scratch, burr and foreign‑metal contamination.
-
Issued documents: EN10204 3.1 / 3.2 certificate, full chemical report, mechanical test record, batch traceability file for medical audit.
9. Export Packaging & Shipment
-
Inner packing: Medical‑grade anti‑rust film + independent soft protective sleeve for each single bar, avoid cross‑contamination.
-
Outer packing: Dedicated fumigated export wooden case, isolated shock‑absorbing filling, prevent scratch and collision.
-
Marking: Laser permanent marking grade, standard, diameter, heat number on bar end.
-
Trade terms: FOB, CIF, DDP; air freight preferred for medical‑grade small‑batch orders.
