Niobium foil, sheets and plates
Niobium and niobium alloys
-
Pure niobium
Niobium, like all refractory metals, shows high mechanical strength and hardness. Its corrosion resistance is slightly weaker at high temperatures compared to tantalum. However, niobium is more cost-effective in certain applications.
Niobium sheets and foils are often used in chemical and medical industry. Nuclear technology utilizes the low capture-cross section for thermal neutrons.

NbZr1
Alloying 0.8 to 1.2% zirconium to niobium significantly increases its strength and hardness. If you are looking for good mechanical properties, NbZr1 should be considered.
