Flux composition
A flux composition includes a component (A) that is a powder of an alkali metal zinc fluoroaluminate represented by "MwZnxAlyFz (1)" (wherein M is K or Cs, and w, x, y, and z are a positive integer, the greatest common divisor of w, x, y, and z being 1), the content of the component (A) in...

Zusammenfassung: | A flux composition includes a component (A) that is a powder of an alkali metal zinc fluoroaluminate represented by "MwZnxAlyFz (1)" (wherein M is K or Cs, and w, x, y, and z are a positive integer, the greatest common divisor of w, x, y, and z being 1), the content of the component (A) in the flux composition being 50 mass % or more. The flux composition prevents occurrence of a brazing defect and discoloration even when an aluminum alloy is brazed in an atmosphere having a high oxygen concentration, or an atmosphere having high humidity. |
