Hafnium wire is relatively soft, so it is easy to roll and forge. Hafnium can also be machined. Care must be taken during processing, as hafnium can easily ignite when finely ground into powder chips. Hafnium does not burn when compact.

Hafnium's chemical properties are comparable to those of titanium and zirconium; in chip form and especially in powder form, hafnium is very reactive, i.e. it is highly flammable and explosive. In closed form it is rather inert, but this changes at higher temperatures. At temperatures above 700 °C, hydrogen is absorbed very quickly, and hafnium wire also reacts with water, oxygen, nitrogen and hydrogen.

Hafnium wire is resistant to acids with the exception of hydrofluoric acid. It is resistant to water and water vapour up to 400 °C and has good corrosion resistance to acids and alkalis up to 100 °C.

Hafnium is not attacked by alkalis, even by boiling caustic soda mixed with sodium peroxide.

Properties of hafnium wire:

• good machinability
• good heat resistance
• excellent corrosion resistance
• good resistance to alkalis

Main application of hafnium wire:

• Gas industry
• automotive industry
• shipbuilding
• Chemical and food industry
• construction industry
