PROBLEM TO BE SOLVED: To provide, at a low cost, a soldering iron that is superior in heat conductivity and durability and that is equipped with a tip end made of copper/iron alloy requiring no plating. SOLUTION: The soldering iron is constituted of the tip member which is heated by a heater and an tip end part which melts solder by heat from this tip member to make the solder stick to a part to be soldered. The tip end part is a copper/iron alloy composed of 40-95 mass % iron, 1-15 mass % at least 1 kind or more of Al, Ni, and Mn, and the balance copper, while the tip member is a copper/iron alloy composed of 1-30 mass % iron and the balance copper. In addition, these copper/iron alloys are joined to each other by spot welding or brazing in the structure. Particularly, the soldering iron has no iron plating or chrome plated layer in the tip end part. COPYRIGHT: (C)2005,JPO&NCIPI |
