ASTM F1472 Ti6Al4V Alloy For Surgical Implant

Description

ASTM F1472 Wrought Titanium-6 Aluminum-4 Vanadium Alloy for Surgical Implant Applications (UNS R56400)

ASTM F1472 covers the chemical, mechanical, and metallurgical requirements for wrought annealed titanium6 aluminum-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 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
