Description Of UNS R60702 Zirconium Foil
UNS R60702 Zirconium Foil is a thin, flexible sheet of high-purity zirconium metal manufactured to ASTM B551 standard. It is produced from high-purity zirconium sponge or crystal bars through vacuum arc remelting (VAR), forging, hot rolling, cold rolling, and precision annealing processes. The foil is available in thicknesses from 0.01mm to 0.5mm, widths up to 300mm, and custom lengths.
Zirconium is a silver-grey transition metal with a density of 6.51 g/cm³ and a melting point of 1852°C. It offers outstanding corrosion resistance in hydrochloric acid, sulfuric acid, nitric acid, acetic acid, and strong alkalis. Its low neutron absorption cross-section makes it indispensable in the nuclear industry for fuel cladding and core structural components. Zirconium also has a strong affinity for oxygen, nitrogen, and hydrogen, making it an effective getter material in vacuum tubes, electronic devices, and high-purity gas purification systems.
UNS R60702 zirconium foils are widely used in nuclear reactor components, chemical processing equipment, electronics, getters, optical coatings, medical devices, and research laboratories. The foil can be supplied in bright, pickled, polished, or annealed condition, with custom thicknesses, widths, and shapes available upon request. All products are manufactured under ISO 9001 quality systems and comply with ASTM B551 / ASME SB-551 standards.
