Decades of hands-on metallurgical experience solving titanium's unique machining challenges through engineered process solutions.
Problem — Titanium's poor heat dissipation (≈ 7 W/m·K) causes rapid tool-edge temperatures exceeding 1,000°C, accelerating flank wear and compromising surface integrity.
High-pressure coolant delivery at 70+ bar directly to the cutting zone evacuates heat instantly, prevents built-up edge formation, and extends tool life by up to 300%.
Problem — Titanium's low elastic modulus (≈ 110 GPa) induces workpiece deflection and regenerative chatter during machining, especially in thin-wall and deep-cavity geometries.
5-axis simultaneous machining with rigid fixturing and dynamic vibration damping eliminates chatter marks and holds micron-level tolerances on complex titanium structures.
Our process engineers have logged over 50,000 hours of titanium-specific machining across all 7 grades.

Common questions from procurement engineers, design engineers, and quality teams specifying titanium alloys for aerospace, medical, chemical, and industrial applications.
Choose Grade 1 or 2 (CP-Titanium) for chemical processing, marine, and medical implants where corrosion resistance and formability matter most. Choose Grade 5 (Ti-6Al-4V) for aerospace structural parts, automotive, and high-stress applications requiring the best strength-to-weight ratio. Choose Grade 23 (Ti-6Al-4V ELI) for surgical implants and medical devices requiring extra-low interstitial content and superior fatigue performance.
Both are Ti-6Al-4V alloys with identical nominal composition, but Grade 23 (ELI = Extra Low Interstitial) has tighter limits on iron, oxygen, and nitrogen impurities. This gives Grade 23 superior fracture toughness, fatigue life, and biocompatibility — required for ASTM F136 surgical implants. Grade 5 (ASTM B265 / AMS 4911) is used for aerospace structural components per AMS 4928 and AMS 4965.
Yes. Every shipment ships with full EN 10204 Type 3.1 mill certification including heat number, chemical composition, mechanical properties (ultimate tensile strength, yield strength, elongation), and country of origin. For aerospace and medical programs we also provide AS9102 first-article inspection reports, dimensional inspection reports per ISO 2768, and batch-level traceability to ASTM E415 / ASTM E2371 spectrometric analysis.
Standard milling tolerance is plus or minus 0.025 mm (plus or minus 0.001 inch) on critical features per ISO 2768 m-k. Tight tolerance machining down to plus or minus 0.005 mm is available for bearing seats, threaded ports, and medical implant mating surfaces. Surface finishes of Ra 0.4 micrometer (16 microinch) or better are achievable through precision grinding and lapping.
Standard lead time is 3-7 days for prototypes (1-10 pieces), 2-4 weeks for pilot runs (10-100 pieces), and 4-8 weeks for production volumes (100-5,000+ pieces). Lead time depends on material certification requirements (Type 3.1 mill cert vs. full batch traceability), part complexity, and surface finishing specifications. Expedited 48-hour turnaround is available for emergency prototype work through our fast-track manufacturing cell.
Yes. We manufacture under AS9100D quality management system for aerospace and NADCAP-accredited special processes.
