Chalco Titanium's production capacity
Cold-rolling facility and dimensional capability
Chalco Titanium operates a physical cold-rolling plant in Wujiang, Suzhou, specializing in the R&D and production of precision metal materials. With a workshop area of several thousand square meters, it is capable of:
- Thickness range: approx. 0.003–0.20 mm (3 μm–0.20 mm)
- Width range: approx. 80–420 mm
This means Chalco Titanium can cover products from micron-level ultra-thin titanium foil up to around 0.2 mm medium-thickness titanium strip, meeting thickness requirements for various structural components.
Key equipment
Precision cold-rolling equipment
With an effective rolling thickness of approx. 0.003–0.20 mm and strip width of 80–420 mm, it supports multi-pass precision rolling for ultra-thin and very thin titanium foil/strip. Through multi-pass precise reduction and process control, it balances shape control and flatness, ensuring thickness tolerance can be kept within ±1–3%, providing a foundation for stable mass production of ultra-thin titanium foil.
Precision slitting equipment
Capable of slitting master coils into various widths from 80 to 420 mm to match die-width requirements for smartphones, FPCs, batteries, and more. The slit edges are neat with minimal burrs, meeting the consistency requirements for edge quality in high-speed precision stamping and roll-to-roll processes, helping improve downstream efficiency and yield.
Annealing and heat-treatment equipment
By adjusting protective atmosphere, heating/cooling profiles, and soaking schedules, it can flexibly match the strength/ductility window required by different products—enabling both high-strength, low-ductility TC4 strip and thin strip in spring temper with better formability. This ensures stable, repeatable mechanical properties from sampling through mass production.
Cleaning and surface-treatment line
Provides degreasing, cleaning, and surface finishing for rolled titanium foil/strip, effectively removing rolling oil and surface contaminants to improve surface cleanliness and consistency, delivering higher adhesion and reliability for subsequent processes such as coating, etching, plating, and bonding.
Supporting inspection and laboratory equipment
Includes thickness measurement, surface roughness inspection, and mechanical property testing. Key batch parameters are recorded and traceable, forming a closed-loop quality control system from master coil to finished product, ensuring consistent performance of ultra-thin titanium foil and very thin titanium strip across batches.
