Flux cored solder wire

Non-cleaning type for aluminum EAN series
Solderable to aluminum

Use special fluorine compound as the activater.Strong activation enables to solder to aluminum parts which is so difficult to solder.

Solderable to aluminum

●Soldering example


Suppress the corrosion and achive to secure the reliability after soldering. Cleaning of flux residue is not required like the general flux cored solder wire.


●Copper plate corrosion test

Strong activity and low corrosivity stand side by side

Progressive application

Enables to solder to aluminum wire, which was impossible in the past, and to allow for the introduction of aluminum wire in wide range of applications.
