Titanium foil is a
titanium plate,
titanium strip, titanium roll or
titanium sheet with a thickness of 0.1mm or less. Another indicator for assessing the thickness of titanium foil is the weight per unit area, such as g/m or oz/fi, etc. The larger the value, the larger the thickness. The width of the titanium foil is cut according to the user's requirements. However, the larger the width during manufacture, 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 aerospace, navigation, nuclear power, electronics, chemical industry, petroleum, precision manufacturing, medical and pharmaceutical, etc.
The production methods of titanium foil include rolling and heat treatment.
Rolling:
The manufacturing method of titanium foil is flat roll strip rolling, which is the most widely used, with high productivity, large scale and output. Basically use a six-roll cold rolling mill or a 20-roll cold rolling mill for production.
Heat treatment:
There are two mainstream heat treatment methods for titanium strip and foil: vacuum annealing and continuous online protective annealing. Vacuum annealing is to place the rolled or sheet titanium foil in a vacuum furnace for heat treatment; the continuous online protective annealing of titanium strip and 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 performance indicators of titanium strip and foil.
