Fe erosion prevention solder alloy, cored wire solder, wire solder, cored wire solder, flux coated solder, and solder joint

摘要

A solder alloy for preventing iron erosion that suppresses tip erosion and suppresses the adhesion of carbide to the tip, in order to prolong the life of the tip of the iron tip, and insert solder, wire solder, and core insert. Provide wire solder, flux coated solder, and solder joints. Ag: 0.2 to 4.0%, Cu: 0.1 to 1.0%, Co: 0.01 to 0.04%, Ni: 0.025 to 0.1%, Fe: 0% by mass 0.007 to 0.015%, the balance is an alloy composition made of Sn, and is used for preventing Fe erosion in which adhesion of carbide to the tip of the iron is suppressed.
