Micro-Tubing Metallurgy: ASTM F136 vs. ASTM F67 for Medical Assemblies
Precision medical tubing requires uncompromising chemical purity, tight concentricity tolerances, and predictable microstructural behavior. Jiaxing Wexra Titanium Products provides medical-grade capillary and seamless micro-tubing calibrated explicitly for device fabricators, cardiovascular stent manufacturers, and orthopaedic OEMs.
Commercially Pure (CP) Grade 2 titanium (ASTM F67) provides exceptional ductility, optimal cold workability, and superior corrosion resistance in saline biological environments. Conversely, Grade 5 ELI (ASTM F136 Ti-6Al-4V Extra Low Interstitial) offers reduced oxygen, nitrogen, and carbon limits to enhance fracture toughness and dynamic fatigue resistance.
Key Engineering Metric: Interstitial elements are strictly governed to ≤0.13% Oxygen (O) and ≤0.012% Hydrogen (H) to prevent micro-brittleness during cryogenic draw stages and high-frequency laser welding.
| Standard / Alloy | Tensile (MPa) | Yield (MPa) | Elongation (%) | Primary Application |
|---|---|---|---|---|
| ASTM F67 (Gr2 CP Ti) | ≥ 345 | ≥ 275 | ≥ 20% | Pacemaker leads, IV drug lines, endoscopy sheaths |
| ASTM F136 (Gr23 Ti-6Al-4V ELI) | ≥ 860 | ≥ 790 | ≥ 10% | Orthopaedic nail sleeves, bone marrow cannula, spinal cages |
| ASTM B338 (Gr2 Tubing) | ≥ 345 | ≥ 275 | ≥ 20% | Biomedical heat exchange, sterile fluid lines |
| Grade 5 (Ti-6Al-4V Standard) | ≥ 895 | ≥ 828 | ≥ 10% | Surgical robotic articulation pins, structural housings |

Eastern Indonesia Healthcare Integration
Localized Application Scenarios in Makassar
As the primary commercial and healthcare gateway of South Sulawesi, Makassar is undergoing rapid clinical modernization. Our titanium medical tubing directly supports the strategic operational sectors across the metropolitan health network.
Regional Tertiary Hospital Infrastructure
Central referral centers such as RSUP Dr. Wahidin Sudirohusodo and affiliated academic medical faculties in Makassar require high-integrity biomedical hardware for laparoscopic reconstruction, orthopaedic trauma kits, and intramedullary interlocking nail sets fabricated from ASTM F136 seamless drawn tubing.
Marine & Tropical Atmospheric Sterility
Makassar's maritime port atmosphere presents aggressive ambient salinity and elevated humidity levels. Titanium medical tubing forms an instantaneous, passive titanium dioxide (TiO2) protective film, outlasting 316L stainless steel surgical instruments by preventing crevice pitting during high-temperature autoclave sterilization cycles.
Local Medical Device Assemblers & Lab OEMs
Emerging clinical engineering laboratories and diagnostic equipment providers in South Sulawesi leverage our customized thin-wall micro-tubing (OD 0.20 mm to 12.0 mm) for precision reagent fluidic dispensers, micro-cannulas, and non-magnetic biopsy guidance probes.
Industry & Policy Forecast
Medical Device Industrialization Trends in Eastern Indonesia
Strategic shifts in national healthcare procurement, regional trade connectivity, and domestic production goals are shaping the sourcing demands of Makassar procurement teams.
TKDN Compliance & Local Sourcing
The Indonesian Ministry of Health continues to incentivize domestic manufacturing under Tingkat Komponen Dalam Negeri (TKDN). Local medical assemblers in Makassar require raw, certified titanium hollow stock to execute final machining and assembly locally.
Makassar as the Logistics Hub
With the expansion of the Makassar New Port (MNP) and direct maritime feeder channels to East Asia, procurement transit times for specialized raw materials from our Jiaxing hub are compressed compared to routing via Jakarta or Surabaya.
Minimally Invasive Surgery Adoption
Specialty private and military hospitals in South Sulawesi are actively investing in laparoscopic, endoscopic, and transcatheter technologies, increasing demand for ultra-flexible, seamless titanium micro-tubes with micro-drilled laser ports.
Strict Bio-Audit & REACH/RoHS Demand
Private hospital procurement boards now enforce strict supplier traceability, ensuring that all implant-grade tubular items are free of hazardous residual drawing lubes and pass ISO 10993 cytotoxicity protocols.

Procurement Guide
Makassar Procurement FAQs: Medical Titanium Tubing
Clear, technically precise answers tailored to hospital engineers, private clinic directors, and device importers across Sulawesi Selatan.
How does Wexra arrange delivery to Makassar port or Sultan Hasanuddin Airport?
We provide flexible CIF or DDP solutions serving Makassar. Urgent small-volume micro-tubing orders can be dispatched via air express (DHL/FedEx) arriving at Sultan Hasanuddin International Airport (UPG) in 4-6 business days. Commercial bulk orders are containerized directly to Makassar New Port (MNP) with complete import customs documentation.
What is the minimum wall thickness and tolerance capability for custom draws?
Our precision cold-drawing lines can achieve ultra-thin walls down to 0.05 mm (0.002 inches) with outer diameters starting at 0.20 mm. Outer diameter (OD) and inner diameter (ID) tolerances can be maintained within ±0.005 mm depending on the alloy grade and temper specification.
Can you provide custom laser-cutting and end-forming on titanium medical tubes?
Yes. Under our OEM/ODM service contracts, we offer Swiss-type CNC precision turning, multi-axis laser cutting (for slotted hypotubes and stent geometries), tube flaring, necking, bevel cutting, and electro-chemical deburring to eliminate internal micro-burrs.
What quality certification documents accompany clinical shipment batches?
Every batch includes an official EN 10204 3.1 Material Test Certificate displaying physical test data (tensile strength, yield, elongation) and chemical spectrographic analysis verifying low interstitial elements. Hydrostatic or eddy current test reports are included for seamless hollow sections.
