Title:
RHENIUM-TUNGSTEN ALLOY WIRE AND METHOD FOR PRODUCING SAME, AND MEDICAL NEEDLE
Document Type and Number:
WIPO Patent Application WO/2023/190832
Kind Code:
A1
Abstract:
A rhenium-tungsten alloy wire according to an embodiment is formed of a tungsten alloy containing rhenium, in which, in an arbitrary measurement area in which a unit area on the wire surface is 50 µm in diameter, a ratio W/Re between an atomic concentration (atm%) of tungsten (W) and an atomic concentration (atm%) of rhenium (Re) obtained by the XPS analysis is 2.5 or greater. The rhenium-tungsten alloy wire according to the embodiment is used in a medical needle according to an embodiment.
