Tantalum Sheet, Tantalum Plate
Tantalum sheet is a flat, thin and rectangular metal piece made of tantalum. Tantalum is a rare, hard, and corrosion-resistant metal that is widely used in various industries such as aerospace, medical, and chemical processing due to its unique properties. Tantalum sheet is often used for its excellent corrosion resistance and high-temperature strength in various applications including chemical processing equipment, nuclear reactors, and capacitors. Tantalum sheets can be produced by various manufacturing methods such as rolling, forging, and drawing, and can be further processed into tantalum foils, strips, and plates. The thickness of tantalum sheets can vary from a few micrometers to several millimeters depending on the application requirements.
