Description
Titanium foil is a thin titanium product in the form of plate, strip, roll, or sheet with a thickness of 0.1 mm or less.
Another measure of foil thickness is weight per unit area (g/m² or oz/ft²) — the greater the value, the thicker the foil.
The width of the titanium foil is cut according to user requirements; however, wider foils generally improve production efficiency.
The maximum width of rolled titanium foil is about 600 mm.
Titanium foil is characterized by its light weight, high strength, corrosion resistance, and excellent formability, making it ideal for high-tech and industrial applications.
