Niobium - Zirconium / Foil
Description
Niobium-Zirconium (Nb-Zr) alloys refer to the alloys composed of zirconium added to metal niobium. Adding zirconium to niobium can improve the strength of the alloy without affecting the plasticity and machining properties of the alloy. Zirconium can also improve the oxidation resistance and alkali metal corrosion resistance of the alloy. They have many advantages, such as high melting point, corrosion resistance, and good cold working performance characteristics.
Alfa Chemistry specializes in providing high quality Niobium-Zirconium foils on the market today. We can also customize various shapes of niobium-zirconium alloy products according to your requirements or drawings.
