Typical applications of gr2 titanium foil

Aerospace

Gr2 titanium foil is widely used in aircraft skins, engine components, thermal insulation and electromagnetic protection layers due to its light weight and corrosion resistance, helping to reduce structural weight and extend service life.

Medical devices

Gr2 titanium has good biocompatibility and meets ASTM F67 standards. It is commonly used in medical applications such as cardiovascular stents, implantable battery housings, and microsurgical devices.

Energy and chemicals

In a highly corrosive environment, Gr2 titanium foil exhibits excellent stability and is suitable for use in key structures such as reactor linings, fuel cell bipolar plates, and battery current collectors.

Scientific research and electronics

Gr2 titanium foil is commonly found in precision electronic and scientific research devices such as electron beam equipment, vacuum system X-ray windows, high-purity containers, and speaker diaphragms for high-end audio.

Production process and quality assurance

Gr2 titanium foil is produced using a high-precision, multi-stand cold rolling process, achieving micron-level thickness control and widths up to 444 mm. During production, vacuum or bright annealing processes are used to ensure a uniform and clean surface, preventing discoloration and defects.

To ensure the coil's straightness and dimensional stability, the product undergoes tension leveling and clean-room slitting. Furthermore, eddy current and ultrasonic testing technologies are used during quality inspection to effectively eliminate internal defects, and burrs are strictly controlled during edge processing.

Through the above process, Gr2 titanium foil not only meets international standards in performance, but also ensures high consistency and traceability between batches.

Surface treatment

• Bright annealed surface - surface finish can reach Ra ≤ 0.2μm, suitable for electronics, medical and vacuum sealing scenarios.
• Sandblasted matte surface - Roughness can be adjusted from Ra 0.5 to 1.5μm, which enhances bonding performance and is commonly used for bonding composite materials and structures.
• Chemical polishing - High surface cleanliness, can remove ≤ 5μm oxide layer, ensuring welding and surface coating quality.
• PVD coating or surface modification can increase the surface hardness to HV ≥ 800, significantly improving wear resistance and functional performance.

By precisely controlling surface roughness (Ra 0.2–1.5μm controllable) and cleanliness (residue ≤ 20 mg/m²), customers can obtain high-performance customized titanium foils that meet the needs of welding, bonding or vacuum sealing processes.

Packaging and logistics

• Vacuum packaged and filled with inert gas to prevent oxidation and contamination.
• Add desiccant and use moisture-proof film to prevent moisture during transportation.
• Use end guards and locking rings to prevent the "telescopic effect."
• The outer layer is made of pearl cotton and fumigated wooden box, with multiple anti-collision and shock protection.

Delivery efficiency:

In-stock products are typically available for shipment within 48 hours.

Typical lead times for custom thicknesses and widths are 7–14 days.
