Abstract: 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.

Abstract: The present invention allows a user to select a handle that is ergonomically friendly to a user's hand and replace it with the replaceable handle that is designed to fit over a soldering iron rod. There are a number of advantages to the present invention. One of the advantages is that a user can choose an individual handle with the desired shape, size, color, and material. Another advantage is that since each user has an individual handle, hygiene problems may be minimized. Still another advantage is the cost savings because as the replaceable handle wears out, only the handle needs to be replaced rather than the whole soldering iron.
