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 prevents carbide from adhering to the tip of the tip for long life of the tip of the tip. 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 of which is an alloy composition made of Sn, and is used for preventing Fe erosion in which adhesion of carbide to the tip is suppressed.
