Tantalum Tape

Tantalum strip is a thin, flat refractory metal material produced through repeated hot rolling, cold rolling and stress-relief annealing of high-purity tantalum blanks. It retains tantalum’s superior intrinsic characteristics: ultra-high melting point, remarkable resistance to strong acid corrosion, stable high-temperature oxidation resistance and outstanding ductility. The strip features even thickness tolerance, flat smooth surface, homogeneous grain structure and low impurity content. It can be easily bent, stamped, welded and deep-processed without cracking, with stable electrical and thermal performance under vacuum and high-temperature working conditions.

Thanks to its thin thickness, flexible forming performance and excellent corrosion resistance, tantalum strip serves as indispensable raw material for multiple high-tech industries. It is widely used for tantalum capacitor packaging strips, chemical anti-corrosion lining, vacuum furnace shielding parts, evaporation coating substrates, medical precision accessories and electronic heat dissipation components. Our tantalum strips cover purity grades from 99.9% to 99.99%, with customizable width, thickness and surface treatments including pickling, matte annealing and bright polishing to satisfy customized processing demands of manufacturers and research laboratories.
