コテ先チップ及び電気ハンダゴテ
Document Type and Number:
Japanese Patent JP4634003
Kind Code:
B2
Abstract:
The present invention provides an electric soldering iron which is excellent in oxidation resistance in a hot environment and achieves good heat conductivity without being chrome-plated. In the tip 3 made of copper or a copper alloy, the outer surface of the top portion 3a, except the solder-coated portion 9, is coated with a mixture of aluminum powder and flux. The surface is reformed into a Cu-Al alloy layer 10-1 which is high in aluminum concentration by melting aluminum powder alone in an inert gas atmosphere.
