| Magnesium is also used as a reducing agent in the production of titanium, beryllium, zirconium, hafnium and uranium. |
| In contrast with tungsten, hafnium does not interact readily with iron-rich material, but it does combine readily with the elements in rocks lacking in iron. |
| Some compounds of hafnium are also used as refractory substances to line the inside of high-temperature ovens. |
| For most of history, hafnium and zirconium were not clearly distinguished from each other. |
| The lanthanides make up the elements between barium and hafnium in Row 6 of the periodic table. |
| Our main materials of manufacture include: zirconium, titanium, steels, hafnium, nickel and copper alloys. |
