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

No-Clean Brazing Flux for Joining Aluminum to Copper
Clean and prepare surfaces before joining aluminum to copper. With minimal residue, this flux does not require cleanup.
TIG Welding Rods for Aluminum
Weld aluminum with these rods.
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 rods are for aluminum 43, 356, 3003, 3004, 5052, 6061, and 6063.
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.
