Alu Brazing Flux

DESCRIPTION

ALU BRAZING FLUX -1 is a powder flux for brazing aluminum and aluminum -based alloys, with an active temperature range of 345C 690C/650F 1,280F.It promotes strong braze joints in aluminum alloys, without melting the substrate metals. The flux wets the joining surfaces thoroughly and prevents the entrapment of aluminum oxide inclusion s in the joints.

APPLICATIONS

ALU BRAZING FLUX -1 is used primarily with gas-oxygen torches, but works in select induction and furnace brazing applications of aluminum metal and most common alloys.

ALU BRAZING FLUX -1 is formulated for use with aluminum brazing filler metal alloys 4047/718 (585-592C/1080-1095F) and 4145/716 (575-580C/1060-107 0F).

DIRECTIONS

ALU BRAZING FLUX -1 is formulated for use in powder form or mixed with water to make a paste. Best results can be obtained by following these guidelines:

( A ) Base metals should be cleaned thoroughly to remove dirt, grease and other impurities.

( B ) Heat the end of filler metal rod and dip into flux , or sprinkle flux on work-piece.

( C ) At temperature, flux liquefies and flows into joints, removing surface oxide and impurities.

( D ) Continue heating until the filler metal melts and fills the joint, producing shiny fillets.

( E ) Flux residues are completely soluble in hot water.

( F ) Flux is hygroscopic. Store in plastic with desiccant bags away from moisture and heat.

SAFETY PRECAUTIONS

ALU BRAZING FLUX -1 contains chemicals that require this flux be used only in well-ventilated areas.

**** Wear NIOSH approved gloves, goggles, and ventilation masks.

**** Avoid contact with skin, eyes and clothing.

**** Avoid breathing dust and fumes produced during soldering processes.

**** In case of eye contact, flush eyes with water and call a physician immediately.

Store flux in cool, un-humid environment in a very tightly sealed container. Desiccant bags are recommended to prevent hygroscopic absorption of humidity into the flux.

ALU BRAZING FLUX -1 has a two (2) year shelf life when stored properly
