Alloy for soldering iron bit

Abstract

Abstract PURPOSE:To obtain an alloy for soldering iron bits excellent in durability by specifying a composition consisting of Cr, Co and Fe. CONSTITUTION:The alloy for soldering iron bits consists of 18-36% Cr, 5-18% Co and the balance essentially Fe, which has superior corrosion resistance to Pb-Sn type solder and also excellent practical durability. Moreover, the above alloy is excellent in the wettability of solder and is increased in thermal capacity and reduced in temp. changes, so that is can be suitably used for carrying out the automation of soldering continuously over a long period. As to the above composition, when Cr is <18%, corrosion resistance is deteriorated and, when >36%, formability is deteriorated; when Co is <5%, corrosion resistance is deteriorated and, when >18%, raw material costs are raised.
