ASTM F1472-Wrought Titanium-6Aluminum-4Vanadium Alloy for Surgical Implant Applications

ASTM F1472 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

Product Analysis Tolerance

Annealed or Annealed and Stress Relieved Mechanical Properties

^A Mechanical properties for conditions other than those listed in this table may be established by agreement between the supplier and the purchaser.

^B Tensile and yield strength requirements apply in both the longitudinal and transverse directions.

^CElongation of material1.575 mm [0.062 in.] or greater in diameter or thickness shall be measured using a gage length of 50 mm [2 in.] or 4D or 4T. Elongation of material under 1.575 mm [0.062 in.] in diameter or thickness may be obtained by negotiation.

^D Applies to bar, plate, and forgings only. L= longitudinal; LT= long transverse; ST = short transverse.

^ETransverse requirements in Table 3 apply only to product from which a tensile specimen not less than 63.5 mm [2.50 in.] in length can be obtained.

^FMaterial tested in the short transverse direction need not be tested in the long transverse direction.

^G Bend test applicable to sheet and strip products: T = thickness of bend specimen in reference to diameter of bend. (Bend factor is the mandrel diameter.)
