Question

The ASTM F-90 Co-Cr-W-Ni alloy has the following composition: Co: 45.5~56.2 Cr: 19.0~21.0 W: 14.0~16.0 Ni: 9.0~11.0 Fe: 3.00 max Mn: 1.0~2.0 C: 0.05~0.15 P: 0.04 max Si: 0.40 max S: 0.03 max You are in charge of quality control of incoming materials at a biomedical devices company. One of your engineers intends to use this alloy to fabricate an implant. Another engineer in your team objects to its use because of the high Ni content which can trigger an allergic reaction in some patients. What steps, including tests and analysis, would you take to resolve this issue?

Explanation / Answer

i will immediately call upon quality control and metallurgical department and will order to run some test on the specific substance like ultraviolet diagnaurtopy.It will let us know what is feasible
