Niobium foil, sheets and plates
Niobium and niobium alloys
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.
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.
