TIP OF SOLDERING IRON, PROCESS FOR PRODUCING THE SAME, AND ELECTRICAL SOLDERING IRON AND ELECTRICAL SOLDER SUCKING IRON INCLUDING THE IRON TIP

摘要

Iron tip (2) for soldering for use as the tip of an electrical soldering iron (copper) or electrical solder sucking iron (copper), comprising tip core material (10) of copper or copper alloy having its front end fitted with iron forefront member (20) constituted of a metal particle sintering compact produced according to the powder metallurgical process. In the metal particle sintering compact, use is made of a sintering base material consisting of an appropriate combination of the respective particles of iron, nickel and cobalt optionally together with a first sintering auxiliary material consisting of an appropriate combination of the respective particles of copper, silver, tin, boron and carbon and a second sintering auxiliary material consisting of an appropriate combination of the respective particles of vanadium, niobium, tantalum, chromium and molybdenum.
