1、 Basic Definition and Characteristics

TA1 titanium foil is an ultra-thin metal strip made of high-purity titanium metal, with a thickness typically between 0.005-0.1mm. As a foil form of industrial pure titanium, it has the following significant characteristics:

1. Physical properties: Density of 4.5g/cm ³ (only 57% of steel), Vickers hardness of 120-150HV, thermal conductivity of 16.4W/(m · K), coefficient of linear expansion of 8.6 × 10 ⁻⁶/℃ (range of 20-100 ℃);

2. Chemical properties: It has good corrosion resistance to most acid, alkali, and salt solutions, especially exhibiting excellent performance in oxidizing media. The surface can form a dense passivation film to prevent further corrosion;

3. Mechanical properties: The room temperature elongation can reach over 30%, combining high strength and good weldability;

4. High temperature performance: maintains high strength in the temperature range of 550-700 ℃;

2. Main application areas

TA1 titanium foil has been widely used in multiple high-end fields due to its excellent performance:

Aerospace: engine blades, fuselage frame, skin, high strength, high temperature resistance, lightweight;

Electronics industry: speaker diaphragm, precision electronic components, high fidelity, clear and bright sound;

Chemical equipment: heat exchangers, reactor liners, pipelines, resistant to strong corrosive media, reducing maintenance costs;

Marine engineering: ship accessories, seawater desalination equipment, resistant to high salt environments, extending equipment lifespan;

Automotive industry: Diesel engine pistons and connecting rods improve performance and fuel economy.

TA1 titanium foil, as a high-performance metal material, has irreplaceable advantages in the high-end manufacturing field. With the continuous improvement of production technology, its application scope will further expand.
