Tantalum Foil
Tantalum Foil
Tantalum foil is a thin sheet of tantalum metal that is commonly used in various applications in electronics, aerospace, and chemical industries. Tantalum foil is known for its excellent corrosion resistance, high melting point, and good electrical conductivity. It is often used as a protective coating or barrier layer in electronic components, as a heating element in high-temperature furnaces, and as a component in capacitors.
Tantalum foil is typically produced by rolling or annealing tantalum sheets to a thickness of a few microns to a few millimeters. It is available in various grades and sizes, depending on the application requirements. Tantalum foil is also characterized by its high ductility, which allows it to be easily formed into different shapes and sizes.
