Stick Electrodes for Aluminum
Weld aluminum 3003, 3004, 5052, 6061, and 6063 with these E4043 electrodes. They’re good for welding dissimilar grades of aluminum and heat-treated aluminum parts. The flux coating produces good stability, speed, and welding performance.
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.

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.
Low-Melting-Point Solder for Low-Temperature Applications
Even as temperatures approach absolute zero, this indium solder remains soft and malleable, allowing it to form an airtight seal between metal and certain non-metal materials. It’s often used in cryogenic applications, including those with liquid nitrogen. This solder has a lower melting point than most solders, so it’s good for sensitive assemblies, such as semiconductors and electronic components. Unlike commonly used tin-based solders, this solder won’t damage gold plating on circuit boards. It’s also a good conductor of heat and electricity. More durable than standard tin-lead solder, this solder is less likely to crack from repeated temperature swings. It’s low outgassing, so it’s good for use in high-vacuum applications.
This indium-based solder can be cold welded, meaning it will bond to itself without heat. You can also use it for step soldering with traditional solders. It does not have a flux core; choose soldering flux to prepare workpieces for this solder.
Leaded solder has greater tensile strength and density than other indium-based solders, giving it a stronger hold.
Lead-free solder is safer to use than leaded solder and helps meet industry regulations. Solder that is 100% indium has better thermal conductivity than solder that contains tin, and will cold weld more easily. However, it has lower tensile and shear strength than solder with tin. Solder with 48% tin has greater tensile and shear strength than 100% indium solder, but lower thermal and electrical conductivity.

High-Density Low-Melting-Point Solder
This bismuth-tin solder has similar performance properties to lead solder, but is also safe for use in food-processing equipment and copper water pipes. It has a lower melting point than most solders, so it’s good for sensitive assemblies, such as semiconductors and electronic components, as well as for step soldering with traditional solders. However, it’s less thermally conductive than other metals and more brittle than lead. Flux isn’t required, but for easier cleanup use it with no-clean soldering flux. This solder is lead-free, so it is safer to use than leaded solder and helps meet industry regulations. Do not use this solder on drinking water pipes.
Solder with 1% silver forms stronger bonds than solder without silver. It’s also more malleable and ductile. However, it has a higher melting point, so it takes longer to solder.
