This listing is for the following:
-1/2 pound of Vulcan G-51 Aluminum Brazing Rod (42 rods, 3/32″ diameter, 18″ length)
-4 oz jar of Vulcan Systems G-51 Aluminum Brazing Flux
Description:
Vulcan Systems G-51 Aluminum Brazing Rod is specifically alloyed for use with a torch on all known weldable and brazable aluminums. It is not necessary to melt the base metal when using this product because it works similar to silver brazing alloys that are very fluid. Deposits have good color match to aluminum, high strength, and good electrical conductivity.
Vulcan Systems G-51 Aluminum Brazing Flux is used in conjunction with G-51 Brazing Rod.  It goes from powder to paste to liquid with increased temperature.  The flux thoroughly cleans, quickly melts, and easily spreads the filler metal.
Procedure:
When brazing on thicker pieces of aluminum and/or cast aluminum, an oxygen-acetylene torch is required!  Even on thinner aluminum pieces, oxygen-acetylene is recommended, though a mapp gas torch may be sufficient.
Clean joint area, preferably by mechanical means. For best results, a maximum of .010″ joint clearance should be maintained.  Large sections should be preheated to 600 to 900 degrees F. Use a carburizing flame to heat part broadly.  Heat end of rod, dip into Vulcan G-51 flux and transfer to a joint area. Continue heating until flux liquifies. Melt a small amount of rod onto the joint and continue heating until it flows through the entire joint. Add sufficient alloy to completely fill the joint but use ample flux at all times to prevent contamin-ation from the atmosphere. Allow to coool slowly and then remove all flux residue with hot water and stiff brush.
