Extremely thin titanium strip coils possess outstanding properties such as high-temperature resistance, low-temperature resistance, strong acid and alkali resistance, high strength, and low density. They have been widely applied in multiple fields including aerospace, shipping, Marine engineering, transportation, and military.
Application Area
1.Tweeter films for speakers and horns
In the application of the speaker industry, due to its low hydrogen and iron content, hardness reaching Hvl30 degree, and ductility over 35%, especially the titanium sound film processed and made of ultra-thin titanium foil has become the first choice for high-quality audio equipment, achieving high fidelity and clear and bright sound.
2.Used in the hydrogen fuel cell industry
Bipolar plates are mainly used to separate fuel from oxidants and prevent gas from passing through. It collects and conducts current with high electrical conductivity. It is widely applied in fields such as automobiles, distributed power generation and portable power supplies; It is an important component of hydrogen fuel engines. Metal bipolar plates require high electrical and thermal conductivity, as well as better mechanical strength, gas barrier capacity and impact resistance. Therefore, thinner and lighter metal materials such as titanium foil are needed, which can significantly increase the specific power density.
3.Used for metal composite materials
Many carbon fiber composite materials are used on aircraft. The elastic modulus of titanium alloy and carbon fiber reinforced composite materials is matched, the coefficient of thermal expansion is similar, and they have good chemical compatibility and are less prone to potential corrosion.
4.Used in the vacuum coating industry
Titanium plating is carried out in a high-temperature, vacuum titanium furnace, using titanium and zirconium metals. The glow discharge of inert gas is used to ionize the vapor of metals or alloys. The ions are accelerated by an electric field and deposited on the negatively charged stainless steel plate, thereby forming a rich and bright metal film.
5.The application in the flexible solar cell industry
Titanium foil has good flexibility and is more heat-resistant than polymer materials. It is conductive by itself and does not require the addition of transparent conductive oxides such as ITO. It can be directly used as the photoanode substrate for flexible fuel-sensitized solar cells and is an ideal material for thin-film solar cell substrates used at sea and along the coast.
6.Used in the medical industry
Titanium and titanium alloys are widely used in cranioplasty, made into titanium mesh or titanium foil for repairing the meninges and peritoneum, artificial heart valve stents, and various artificial joints, bone plates, bone screws and fracture fixation needles, etc.
7.Used in the precision instrument manufacturing industry
It is mainly applied in industries such as precision electronic robots, precision components, intelligent machinery, precision parts and instruments for intelligent automotive electrical manufacturing, precision components and materials for computer manufacturing, precision processing of hardware, precision electronic materials and precision components for ships and automobiles, etc.
