Niobium · Cold-rolled — Optical targets and SRF

Niobium Sheet and Foil

Cold-rolled niobium sheet and foil (Nb ≥ 99.9%) from 0.1 mm thick. Used as sputtering targets for Nb₂O₅ optical coatings, liner sheets for chemical equipment, and plate for forming SRF resonant cavities for high-energy physics.

• Thicknesses 0.1-5 mm; standard sizes up to 500 x 200 mm
• Nb >= 99.9% with certificates and GDMS analysis for trace impurities
• High ductility, deep-drawable and formable for reactor lining
• Coefficient of thermal expansion alphaT 7.3 ppm/K, compatible with stainless steel
• Cut to size: guillotine, laser, punching
