PROPERTIES
Hafnium is a silvery-white, lustrous, readily malleable metal. Its physical properties depend strongly on any zirconium impurities. If it possesses a high degree of purity, it is comparatively soft, pliable and thus easy to work with. The more traces of oxygen, nitrogen and carbon it contains, the more brittle it is. In small-particle form, it proves to be very reactive.
In air, hafnium forms a thin, passivating oxide layer that protects the metal from corrosion. Powdered hafnium, on the other hand, burns in air. Hafnium is extremely temperature resistant and is considered to be extremely robust against bases and acids.
Expert tip
"Like any technology metal, the development of demand for hafnium is very closely linked to the economic situation in the manufacturing sectors. If the economy develops positively, the price of the raw material will also rise. As the aircraft industry alone expects demand for more than 36,000 new passenger and cargo jets by 2033, buyers have good opportunities to profit from the expected availability bottlenecks.“ Thomas Grob, Tradium
