Platinum/iridium Wire
Platinum and its alloys have been widely used in the medical field for half a century. Because of their low corrosiveness, excellent radiopaque function and biocompatibility, platinum has become an ideal material for medical intervention. Commonly used platinum family alloys include pure Pt, PtIr10, PtW8, PtNi10 and so on.
Classification:
