No-Flux Brazing Alloys for Aluminum

No need to add flux when brazing aluminum parts such as radiators, power tools, and castings—these alloys don’t require it. All have excellent corrosion resistance. They don’t contain cadmium, so they’re safer than other brazing alloys with cadmium and help you meet industry regulations.

Brazing Alloys for Joining Aluminum to Copper

Join aluminum to copper and copper-based alloys, such as brass and bronze. These alloys don’t contain cadmium, so they’re safer than other brazing alloys with cadmium and help you meet industry regulations.

Brazing Alloys for Aluminum

Join aluminum to aluminum. These alloys do not contain cadmium, so they are safer to use than alloys with cadmium and help meet industry regulations.

BAlSi-3—BAlSi-3 alloys are good for filling in large gaps because they melt into a thicker liquid than BAlSi-4 alloys.

Flux-Included Brazing Alloys for Joining Aluminum to Copper

Flux is already built into these alloys, so there’s no need to add it when joining aluminum to copper. These alloys don’t contain cadmium, so they’re safer than other brazing alloys with cadmium and help you meet industry regulations.

Weld aluminum with these rods.

ER1100—ER1100 rods are for aluminum 1100, 3003, and 5005. Soft and easy to form, they’re often used to weld thin-gauge aluminum and foil. They also resist chemicals and corrosion. Anodize these rods to create a bright finish.

ER4043—ER4043 rods are for aluminum 43, 356, 3003, 3004, 5052, 6061, and 6063.

ER4047—ER4047 rods are for aluminum 43, 356, 3003, 3004, 5052, 6061, and 6063. Choose these rods when leak-tight welds are a must, such as when welding very thin aluminum and products that will hold pressurized liquids or gases. When melted, they flow better than ER4043 rods, so they’ll fill in more of the space between the two pieces of your weld. They also shrink less as they cool, so they’re less likely to distort your weld. Once hardened, they produce a bright finish with little soot. These rods will stand up to prolonged high heat.
