Description

       

   <Desc / Clms Page number 1>
 



   The present invention relates to alloys.



   Industrially pure titanium is characterized by good strength and ductility, as well as a high strength: weight ratio. In some cases, however, it is desirable to have even better properties.



   According to the invention, a titanium-based alloy consists of arsenic in an amount of up to 0.5%, the remainder being titanium, apart from the impurities.



   These alloys have adequate ductility and better strength than commercially pure titanium.



   These alloys can be modified and improved by the addition of alpha and / or beta stabilizing elements.
