    • In an iron tip for a soldering iron, composed of Fe plated copper or copper alloy, an outer surface excluding a solder coating portion in a leading end portion of the iron tip is plated with Cu in a film thickness range of approximately 10 to 50 &mgr;m, the surface is coated with a mixture of Al particles and flux, only the Al particles are melted in an inert gas atmosphere, and the surface is modified into a surface with a Cu—Al alloy coated layer having a high Al concentration. As a result, without using Cr plating, it is possible to provide an electric soldering iron having an excellent resistance to oxidation under high temperature environment and a high heat conductivity.
    • 在由Fe镀铜或铜合金构成的烙铁的铁尖中,铁尖的前端部除了焊料涂敷部的外表面镀有大约10〜50μm的膜厚范围的Cu 表面被Al颗粒和焊剂的混合物涂覆,只有Al颗粒在惰性气体气氛中熔化,并且用具有高Al浓度的Cu-Al合金涂层将表面改性为表面。 结果,在不使用镀Cr的情况下,可以提供在高温环境下具有优异的抗氧化性和高导热性的电烙铁。
