Hafnium Plate and Sheet

HEXON use crystal hafnium as the raw material to melt hafnium ingot by vacuum electron beam furnace. This can enable us to attain higher purity, finer structure and better mechanical properties, which will bring trouble-free finished hafnium products to our valuable customers.

Hafnium plate and sheet are produced by hot/cold rolling on a reverse rolling mill. Cold-rolled hafnium sheets have a metallic bright surface as rolled. Oxide skin of hot-rolled hafnium plate can be mechanically descaled or pickled. Both hafnium plate and sheet are even by leveling and have a defects free surface condition.

We can reach a purity of Zr+Hf 99.95% minimum with content of Zr 1% maximum.

HEXON provide EN 10204/3.1 certification including chemical and mechanical test. We can also custom special element such as oxygen via vacuumization for hafnium finished products.
