FWB201S   Aluminum brazing flux powder

FWB201S aluminum brazing flux is a white powdered flux used with ER4047 aluminum alloy welding wire for flame or induction brazing of aluminum alloys. The flux residue is easily removable with water rinsing. It is widely applied in refrigeration and automotive air conditioning systems for joining aluminum tubes, fittings, and components.

Key Features

Removes oxide films: Effectively removes workpiece oxide films during brazing, promoting welding joint formation.

Improves wettability: Helps liquid wet and spread on base metal surfaces, destroying and dissolving oxide films.

Moisture – proof packaging: Sealed bottle packaging prevents brazing flux from getting damp.

Application

Can be used for torch brazing various common aluminum materials and is often used with ER4047.

Can be sprinkled dry on parts or mixed with water, methanol, ethanol, or isopropyl alcohol to form a paste.

Flux residues can be easily removed with water rinsing.

Widely applied in refrigeration and automotive air – conditioning systems for joining aluminum tubes, fittings, and components.
