It is an ultra-thin metal foil made of high-purity titanium or titanium alloy, featuring unique performance advantages and widely used in multiple high-tech fields.
The basic characteristics of titanium foil are light weight and high strength: The density of titanium (about 4.5g /cm3) is only 60% of that of steel, but its strength is close to that of steel, and it has an excellent strength-to-weight ratio.
Corrosion resistance: In oxidizing media (such as seawater and chloride ion environments), a dense oxide film forms on the surface, and its corrosion resistance far exceeds that of stainless steel and aluminum alloy.
High-temperature resistance: The melting point reaches 1668°C, and the long-term working temperature can reach 400-600°C, making it suitable for high-temperature environments.
Biocompatibility: Non-toxic, non-magnetic, compatible with human tissues, and widely used in medical implants.Thermal and electrical conductivity: Moderate, can be optimized through alloying or surface treatment, suitable for specific electronic scenarios.
Titanium foil manufacturing process:Raw material selection: Commonly used industrial pure titanium (such as Gr1, Gr2) or alloys like Ti-6Al-4V.
Rolling technology: Multi-pass cold/hot rolling, combined with annealing to relieve stress, precisely controlling the thickness to the micrometer level (typical range 0.01-0.2mm).
Surface treatment: pickling, polishing or coating to enhance smoothness and functionality.
Application fields of titanium foil: Aerospace: Engine insulation layers, lightweight components for fuselages, thermal protection systems for spacecraft.
Medical and health care: Orthopedic implants (bone plates, screws), dental restorations, surgical instruments. Chemical energy: Seawater desalination equipment, electrolytic cell electrodes, hydrogen fuel cell bipolar plates. Electronic technology: High-reliability connectors, semiconductor heat sinks, flexible circuit substrates. Emerging fields: 3D printing consumables, flexible battery electrodes, nuclear industry protective materials.
