High purity titanium foil Ti sheet for battery lab research materials

Titanium is a silver-white metal, and its relative abundance ranks 10th among all elements. It is characterized by light weight, high strength, metallic luster, and good corrosion resistance [1]. Because of its stable chemical properties, High temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, high strength, low density, mainly used in aerospace, shipbuilding, military industry, medical equipment and other aspects

Titanium foil is a titanium plate, strip, roll or sheet with a thickness of less than or equal to 0.1mm, and is divided into pure titanium foil and titanium alloy foil.

Another indicator for evaluating the thickness of titanium foil is the weight per unit area, such as g/m or oz/fi. The larger the value, the greater the thickness. The width of the titanium foil is cut according to the user's requirements. However, the greater the width at the time of manufacture, the higher the productivity.

The length of the roll body determines the maximum width of the rolled foil, and the wider, thinner and harder the rolling stock, the harder it is to roll. The maximum width of the rolled titanium foil is about 600mm.

ways to produce:

Electrode preparation→vacuum melting→forging blanking→hot rolling→cold rolling→annealing (heat treatment)→plate, strip, foil

Rolled:

The manufacturing method of titanium foil is the most widely used flat roll belt rolling, which has high productivity, large scale and output. Basically use a six-high cold rolling mill or a 20-high cold rolling mill for production.

Heat treatment:

There are two mainstream heat treatment methods for titanium foil: vacuum annealing and continuous online protection annealing. Vacuum annealing is to place coil or sheet titanium foil in a vacuum furnace for heat treatment; continuous online protection annealing of titanium strip foil is a new technology introduced in recent years, which has higher production efficiency than vacuum annealing, and There is a higher improvement in product quality, but the equipment threshold is relatively high, especially for product quality and mechanical properties of titanium foil .
