Title:
FINE WIRE OF PLATINUM-BASED MATERIAL AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/142849
Kind Code:
A1
Abstract:
According to the present invention, a stranded wire of a platinum-based material is coated with gold or gold alloy and subjected to a wire-drawing process by using dies containing carbon. A fine wire thus prepared is covered with gold or gold alloy, and the coverage rate of gold or gold alloy is 40% or more in terms of area. The fine wire made of this platinum-based material is prepared in a state in which the disconnection of wire during the wire-drawing process is suppressed, and has good performance in terms of electric properties or the like. Furthermore, this manufacturing process can efficiently manufacture a fine wire while suppressing wire disconnection when a fine wire of platinum-based material is manufactured through a wire-drawing process.
