ASTM F1472 Ti6Al4V Alloy For Surgical Implant

ASTM F1472 Ti6Al4V Alloy covers the chemical, mechanical, and metallurgical requirements for wrought annealed titanium6aluminum-4vanadium alloy (UNS R56400) to be used in the manufacture of surgical implants.

1. Strip-Any product under 4.76 mm [0.1875 in.] in thickness and under 610 mm [24 in.] wide.

2. Sheet-Any product under 4.76 mm [0.1875 in.] in thickness and 610 mm [24 in.] or more in width.

3. Plate-Any product 4.76 mm [0.1875 in]. thick and over and 254 mm [10 in.] wide and over, with widths greater than five times thickness. Plate up to 102 mm [4.00 in.] thick, inclusive, is covered by this specification.

4. Bar-Round bars and flats from 4.76 mm [0.1875 in.] to 150 mm [6.00 in.] in diameter or thickness (other sizes and shapes by special order).

5. Forging Bar-Bar as described in 4.4, used in the production of forgings. This product may be furnished in the hot worked condition.

6. Wire-Rounds, flats, or other shapes less than 4.76 mm [0.1875 in.] in diameter or thickness.

7. Billet-Solid semi-finished section hot worked from an ingot whose intended use is for additional hot or cold reduction

8. Other-Other forms and shapes, including tubing, may be provided by agreement between purchaser and supplier
