Core & Bar Solder

Acid Core Solder

Acid core solder is a highly active inorganic acid type of flux (zinc chloride free) for general purpose soldering applications where a flux cored solder wire is desirable.  Rapid soldering can be accomplished on all common metals except aluminum and manganese.  Acid core solder is particularly useful for soldering excessively oxidized metals. 

Please be advised that acid core solder is NOT recommended for electrical or electronic soldering applications due to the corrosive nature of the residue.

Acid Core wire is available in most tin/lead alloys as well as lead-free alloys.

Used in OEM/Industrial applications as well as radiator repair and roofing.

Flux residue is hygroscopic and corrosive.  The work should be allowed to cool undisturbed until the solder solidifies.  The flux residue is then removed with a hot water rinse. For more thorough cleaning requirements, rinse with a 2-10% solution of neutralizer followed by a hot water rinse.
