Brazing & Soldering:
Vulcan G-51 Aluminum Brazing Rod & Flux:
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. Tensile Strength is 35,000 PSI.
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.
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.3/32″ rod 1 lb + Flux $47.99 3/32″ rod 2 lbs + Flux $89.99
High-strength, silver-bearing soldering paste. Free of cadmium, zinc, lead, and other impurities. Leaves bright and shiny, non-tarnishing deposits close to stainless steel in color. Soldered joints are resistant to corrosion and can readily be plated. Has a working temperature of 430 degrees F. Commonly used to join both ferrous and non-ferrous metals when higher strength are required than are normally found with conventional solders. Ideal for use on stainless steel, brass, bronze, copper, nickel, nickel alloys, and carbon steels. Tensile Strength is 15,000 PSI.
Typical Applications include food and dairy equipment, instruments, oxygen lines, sanitary apparatus, and general maintenance repair. Also works great for soldering electrical connections.
Clean joint area. Pre-place before assembly. Apply solder and heat parts with a soft flame. Apply solder and continue heating until flow-out is complete. Add more solder if necessary when it is still molten. Put parts together and heat until alloy becomes liquid. Allow to cool slowly and wash flux residue off with warm water.
Vulcan 310 is a high-strength brazing alloy for general maintenance repair with a torch. At 1400 to 1600 degrees F, the deposit has controlled fluidity, but when the temperature is increased to 1650 to 1750 degrees, the alloy becomes very thin flowing and will produce high strength joints with only .001 to .003″ clearance. Designed to build up and join carbon steels, alloy steels, cast iron, and other non-ferrous materials to themselves or in multiple combinations.
Applications include overlaying and build-up of gear teeth, bearings, shafts, valve seats, wedge bars, and steering knuckles. High temp applications include close fitting joints or broken drills, mill cutters, furniture and bicycle assembly, and attaching carbide cutting tips.
Working Temp is 1400-1750° F, Re-Melt Temp is 1800° F1/8″ 1 lb $42.50 1/8″ 5 lbs $204.99 ($41.00/lb)
Vulcan 320 is similar to 310 but has a lower brazing temperature of 1330 to 1550 degrees F and lower melting point of 1630 degrees F. Applications include overlaying and build-up of gear teeth, bearings, shafts, valve seats, wedge bars, and steering knuckles. High-temp applications include close fitting joints or broken drills, mill cutters, furniture and bicycle assembly, and attaching carbide cutting tips.1/8″ 1 lb $44.99 1/8″ 5 lbs $212.49 ($42.50/lb) 3/32″ 1 lb $45.99 3/32″ 5 lbs $214.99 ($43.00/lb)
