Titanium foil is a titanium plate, strip, roll or sheet with a thickness of less than or equal to 0.1mm. Another index for assessing the thickness of titanium foil is the weight per unit area, such as g / m or oz / fi. The greater the value, the greater the thickness. The width of titanium foil is obtained by cutting according to the user's requirements. However, the wider the manufacturing width, the higher the productivity. The length of the roll body determines the maximum width of the rolled foil. The wider, thinner and harder the rolled piece is, the harder it is to roll. The maximum width of rolled titanium foil is about 600mm. Titanium and alloy foils are mainly used in electronics, aerospace, instrumentation and other departments

Production of titanium foil

Rolling:

Flat roll strip rolling is the most widely used manufacturing method of titanium foil, which has high productivity, large scale and output. Basically, six high cold rolling mill or 20 high cold rolling mill are used for production.

Heat treatment:

There are two main heat treatment methods for titanium strip and foil: vacuum annealing and continuous on-line protective annealing. Vacuum annealing is to place rolled or sheet titanium foil in a vacuum furnace for heat treatment;

Continuous on-line protective annealing of titanium strip foil is a new technology introduced in recent years. Compared with vacuum annealing, it has higher production efficiency and higher improvement in product quality, but the equipment threshold is high, especially in terms of product quality and mechanical properties of titanium strip foil
