TITANIUM -> PROPERTIES
Titanium offers a number of advantages compared to other materials, enabling the development of exceptional and innovative products.
Because of its low weight, with only 56 percent the density of steel, together with high strength and excellent resistance against corrosion and erosion, titanium is suitable for a broad spectrum of applications.
Moreover, titanium is non-toxic and especially biocompatible.
The melting point of titanium is approx. 1680°C.
Titanium is in widespread use today in fields such as medicine, chemistry, mechanical engineering and aircraft construction – wherever materials must meet the highest demands.
