18 months of continuous supply to a listed semiconductor equipment manufacturer Silver-plated fasteners · CNC precision parts · No minimum order quantity
What We Make
Three product lines. Five materials. One standard: yours.
Machined Parts
Precision-machined components in titanium, zirconium, and niobium. Turning, milling, drilling, and grinding to your specifications — from prototype to production runs.
Refractory Metal Parts
Tungsten and molybdenum components for high-temperature and high-wear applications. Sintered, machined, and finished to drawing — with export licensing handled.
Fasteners
Titanium fasteners with optional silver plating per ASTM B700. Proven in semiconductor equipment — 18 months of continuous delivery, zero quality returns.
Why Work With Us
We keep it simple: real materials, real traceability, real delivery records.
No Minimum Order Quantity
Order one part or one thousand. Whether you need a prototype or a production batch, we quote and ship the same way.
Material Certification
EN 10204 3.1 material test certificates provided with every shipment. Full heat-number traceability from raw material to finished part.
ASTM B700 Silver Plating
Silver plating on titanium fasteners per ASTM B700 specification. Applied and verified in a controlled process — not subcontracted and hoped for.
Third-Party Inspection
SGS, BV, or TÜV inspection available on request. Dimensional reports, material verification, and surface finish documentation included.

Based in Baoji — China's Titanium Valley
TINOG is located in Baoji, Shaanxi Province — the industrial hub that produces over 60% of China's titanium and specialty metal output. Our location gives us direct access to raw material, skilled machinists, and a complete processing supply chain: from melting and forging to precision CNC machining.
We don't pretend to be the biggest. We focus on doing one thing well: machining non-ferrous and refractory metal parts to exact specifications, with full material traceability, for industrial buyers who need reliability — not brochures.
