Product Introduction

Pure Titanium Welding Wire ErTi2 For Medical

1. Core Specifications & Standards

AWS Classification: AWS A5.16 ERTi-2 (SAE AMS 4928 compliant)

ASTM Standard: ASTM B863 Grade 2 (UNS R50120)

Dimensions:

Diameter: 1.0–4.0 mm (straight/coil formats)

Length: 1,000 mm standard; custom lengths available

Surface Finish: Bright annealed (oxidation-resistant layer)

2. Technical Advantages

Parameter	Specification	Competitive Edge
Chemical Purity	≤0.16% O, ≤0.08% Al, ≤0.015% N	Minimizes interstitial impurities for weld stability
Mechanical Strength	Yield Strength ≥275 MPa	Balances ductility (elongation ≥20%) and toughness
Thermal Conductivity	17 W/m·K (vs. 45 W/m·K for steel)	Reduces heat distortion in precision welding
Biocompatibility	ISO 10993 certified	Non-toxic, non-allergenic for implants
Magnetic Properties	Non-magnetic	Safe for MRI-compatible devices

3. Key Applications

ERTi-2 titanium welding wire is engineered for critical industries requiring biocompatibility, high-temperature stability, and corrosion resistance:

A. Medical Devices

Implant Fabrication: Welding of titanium alloy (Ti-6Al-4V) hip joint components and dental implants.
Surgical Tools: Precision welding of stainless steel scalpels and forceps (no cross-contamination).

B. Aerospace

Engine Components: Joining titanium turbine blades (resists 600°F oxidation).
Structural Parts: Heat-resistant brackets for satellite deployment systems.

C. Industrial Equipment

Chemical Reactors: Welding of Ti-Pd alloys for seawater desalination membranes.
Hydrogen Fuel Cells: Leak-proof seams in bipolar plates.

4. Manufacturing Process

Raw Material: High-purity sponge titanium (99.9% Ti) melted under vacuum.

Drawing: Controlled reduction to 1.0–4.0 mm diameter (tolerance ±0.02 mm).

Surface Treatment:

Bright Annealing: Removes oxides while preserving surface flatness.

Pickling: Optional nitric-hydrofluoric acid bath for ultra-smooth finishes.

5. Quality Assurance

Third-Party Testing: SGS-certified chemical analysis (Fe ≤0.12%, C ≤0.03%).

Mechanical Validation: Tensile tests per ASTM E8 (post-weld coupons).

Weld Integrity: 100% dye penetrant inspection (ASTM E1417) for cracks.
