PURPOSE:To manufacture a soldering tool with superior hardness, corrosion resistance, wear resistance and long life by mixing one or more out of W, Mo and Cr carbides with highly electrically conductive metal such as Ag or Cu and one or more out of Co, Ni and Fe in the form of powder followed by compacting and calcination. CONSTITUTION:20-50% of powder of at least one kind of metal carbide of high hardness such as tungsten carbide, molybdenum carbide or chromium carbide is mixed with 40-80% of powder of highly electrically conductive metal such as silver or copper and 0.1-10% of powder of at least one of Co, Ni and Fe as a binder for the metal carbide and conductive metal. This mixt. is compacted into a soldering iron and sintered to obtain a soldering tool with good wettability to solder, superior corrosion resistance to solder, high hardness and long life. |
