Alpha-Beta Titanium

The best of both worlds, Alpha-Beta Titanium Alloys are dual-phase dual phase alloys, featuring high compositions of Alpha friendly Aluminium, but with healthy measures of Beta Stabilisers Vanadium, Tantalum, Niobium, and Hydrogen, too. As more Beta Stabilisers are added, so a greater amount of the Beta Phase is retained at lower temperatures. It is extremely common for these alloys to be further strengthened by heat treatment, being quenched from an elevated temperature and subsequently aged at a lower temperature.

 

Of the Alpha-Beta Alloys, it is Grade 5 which is the poster child, accounting for 50% of all Titanium used, with 70% of this being utilised by the aerospace industry. Alpha-Beta Alloys are also commonly employed as medical implants, in consumer goods and sports equipment.

 

All grades, shapes, and specifications of Alpha-Beta Titanium Alloys found below are available directly through Integ Metals, so please feel free to read through the information on this page for reference, or contact us directly with your requirements.
