高周波コイル用線材及び絶縁電線並びに高周波コイル用線材の製造方法
Document Type and Number:
Japanese Patent JP7109938
Kind Code:
B2
Abstract:
To provide a wire rod for high frequency coil used as a coil using an insulation wire, capable of exhibiting stable high frequency property, capable of being manufactured at low cost and having fine diameter, and the insulation wire.SOLUTION: The above described problem is solved by a wire rod 10 for high frequency coil having a central conductor 1 consisting of copper or copper alloy, and a copper iron alloy layer 2 arranged on an outer periphery of the central conductor 1. It is preferable that iron content in the copper iron alloy layer 2 is in a range of 5 to 50 mass%, and that a cross section area ratio of the copper iron alloy layer 2 in total cross section area of the wire rod 10 for high frequency coil is in a range of 5 to 50%.SELECTED DRAWING: Figure 1
