Description
ZhenAn Tantalum Strip and Foil
Unalloyed tantalum meets the compositional limits of ASTM F560 – R05200. Tantalum is selected for its corrosion resistance, thermal conductivity, high melting point, and ability to form dielectric oxide films.
Tantalum is extremely ductile and can be easily cold formed due to its low work hardening rate. Welding can be accomplished by resistance, TIG, or electron beam methods, with care being taken to protect the weld and heat affected zone from the effects of air during welding. Tantalum should not be used for extended periods above 260°C in air or other oxidizing atmospheres unless a protective inert gas or vacuum is provided, due to the potential for hydrogen embrittlement.
Pure Tantalum Foil Available Sizes
Tantalum is available from ZhenAn as strip product from 0.0005" to 0.035" (0.0127 mm to 0.889 mm) in widths up to 12.0" (304.8 mm). The material conforms to UNS R05200 and meets the requirements of ASTM F560 and ASTM B708.
ZhenAn Tantalum Pieces packaging
Our tantalum sheets will be packed in wooden boxes and supported with soft materials to ensure that the products so packed will not move within the wooden box.
