Pure titanium (Ti-6Al-4V and commercial grade 1) has become the fastest-growing frame material in the luxury segment. Weighing just 40–60% of stainless steel while offering superior corrosion resistance and hypoallergenic properties, titanium frames command premium retail price points of $150–500+.
Why Titanium Is Difficult to Manufacture
The challenge lies in manufacturing. Titanium requires:
- Specialized CNC equipment with titanium-grade tooling — standard carbide bits degrade rapidly on titanium’s work-hardening surface.
- Beta-titanium welding in controlled atmospheric environments to prevent oxidation during frame assembly.
- PVD (Physical Vapor Deposition) surface coating for color finishes — traditional electroplating does not adhere reliably to titanium.
- Specialized spring hinge design — titanium’s elasticity requires adjusted hinge tolerances compared to stainless steel.
Chengye’s Titanium Capabilities
CHENGYE OPTICAL has invested in titanium production since 2002, accumulating over two decades of specialized experience. Our titanium CNC line handles everything from ultra-thin 0.8mm wire frames to bold architectural designs popular in European markets. Key capabilities include:
- Japanese 5-axis CNC machining for complex frame geometries
- In-house beta-titanium TIG welding with atmosphere-controlled chambers
- PVD coating line supporting 12 standard finishes + custom colors
- Nickel-free certification per EU REACH SVHC Annex XVII
“For brands entering the premium segment, titanium is no longer optional — it’s the baseline expectation at €200+ retail.”
