Tantalum Wire is a type of wire made from the rare and highly dense metal tantalum. It is known for its excellent corrosion resistance and good thermal conductivity. Tantalum Wire can take hydrogen, oxygen, and nitrogen away from the atmosphere and is ideal for vacuum applications in the lighting industry. It is used in various industries and applications, including electronics, medical, aerospace, and industrial. It can also be used for electrolytic capacitors, electrodes, and rectifiers to make flakes or sewing threads. The typical purity can be 99.5% to 99.99%.
