Hafnium > 0.2% Zirconium Disc

Our range of Hafnium > 0.2% Zirconium Discs offer 25 variations, with a choice of sizes and purities to meet the needs of different applications. Hafnium is a refractory metal known for its high melting point, strength at high temperatures and resistance to corrosion. The addition of a small amount of zirconium further improves the material's mechanical properties. These characteristics make Hafnium > 0.2% Zirconium Discs suitable for uses such as turbine blades, rocket nozzles, and other high-temperature applications where strength and corrosion resistance are required.
