Hafnium Rod and Bar
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 rod and bar are produced from hafnium ingot by forging and further by extruding, rolling, or swaging.
Surface can be machined or centerless ground to reach a precision tolerance -/+0.01 mm (depend on specific diameter).
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.
