Titanium foil is a titanium plate, tape, roll or sheet with a thickness of 0.1 mm or less. 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 larger the width during manufacturing, 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, 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, etc.
