Titanium foil production process
Melting and consolidation
The production of titanium alloy sheets begins with the smelting of titanium ore, where high-temperature processing converts the ore into sponge titanium. The sponge titanium is then compacted and undergoes vacuum arc remelting or electron beam melting to form ingots.
Hot rolling
The ingots are further processed into thinner sheets with thicknesses ranging from 1 mm to 10 mm. This stage involves multiple rolling passes and intermediate annealing to ensure uniformity and ductility.
Cold rolling
After cooling the hot-rolled sheets to room temperature, cold rolling is performed to gradually reduce the sheet thickness to the required foil specifications (typically less than 0.1 mm). Multiple intermediate annealing processes may be required during cold rolling to reduce work hardening and improve ductility.
Precision rolling
Building upon cold rolling, high-precision rolling mills further process the titanium foil to ensure thickness accuracy and surface quality, with thickness control reaching the micron level.
Surface treatment
Treating the surface of titanium foil to enhance quality includes:
- Pickling: removes surface oxides and impurities.
- Polishing: improves surface smoothness to meet decorative or high-quality surface requirements.
- Anodizing: forms a protective oxide layer to enhance corrosion resistance and aesthetics.
Slitting and finishing
- Cutting the titanium foil to specified dimensions based on customer requirements.
- Inspecting the foil's thickness, surface quality, and physical properties to ensure compliance with specifications.
Packaging and shipping
Using moisture-proof and anti-corrosion packaging materials to ensure the titanium foil remains undamaged during transportation and storage.
Including test reports or certifications as per customer requirements.
How to choose the right titanium foil?
When purchasing titanium foil, selecting the appropriate type depends on specific application requirements. Refer to the following guidelines:
- For harsh corrosive environments, choose pure titanium (Grade 1, Grade 2).
- For high strength, high-temperature resistance, and fatigue performance, opt for titanium alloys like Grade 5 (Ti-6Al-4V).
- In the medical field, Grade 23 (Ti-6Al-4V ELI) is typically the best choice, especially for implantable devices and instruments.
- For enhanced aesthetics and corrosion resistance, select anodized or titanium-coated treatments.
- For reduced reflectivity and concealment, choose a matte finish.
- For high gloss and refined appearance, opt for a polished finish.
What factors affect the price of titanium foil?
Titanium alloy type: The composition ratio of different titanium alloys affects the cost. For example, grade 5 (Ti-6Al-4V) is more expensive than grade 2 pure titanium.
Thickness and size: Thinner or custom-sized titanium foil is usually more expensive. For instance, ultra-thin titanium foil with a thickness below 0.01mm costs more than the standard 0.05mm foil.
Surface treatment: Complex surface treatments increase costs. For example, embossed or polished titanium foil is more expensive than a standard matte finish.
Production process: High-precision manufacturing requires advanced equipment and technology. For example, high-precision titanium foil for aerospace applications is more costly than standard industrial-grade foil.
Order quantity and delivery time: Large-volume orders help reduce production costs. For example, ordering 1,000 kg of titanium foil at once has a lower unit price than ordering just 10 kg.
Market supply and demand: When demand is high and supply is tight, titanium foil prices rise. For instance, during peak periods in the aerospace industry, increased demand for titanium foil drives up prices.
