Zirconium offers very good resistance in highly corrosive environments such as acids and alkaline solutions, as well as high toughness. Zirconium is easy to machine, good to weld and fully recyclable. It can be easily processed by rolling, forging and hammering.
Zirconium is passivated in air by a thin, very dense zirconium oxide layer and is therefore inert. It is therefore insoluble in almost all acids, only aqua regia and hydrofluoric acid attack zirconium at room temperature.
Due to its high corrosion resistance, zirconium is a suitable construction material for chemical plants, especially for special apparatus parts such as valves, pumps, pipes and heat exchangers.
As an alloying additive to steel, it also increases the corrosion resistance. Surgical instruments, among other things, are manufactured from the corresponding alloys.
