Join stainless steel with this welding wire.

ER308L wire is for 304 and 304L stainless steel. It creates welds that hold even in cryogenic temperatures.

ER80LSi wire is for 304 stainless steel. It has a higher silicon content than ER308L wire, so it flows more easily when melted and fills in more of the space between the two pieces of your weld. It’s also better where appearance matters because it creates smoother welds.

ER309L wire joins different types of stainless steel. It’s also for use with steel.

ER309LSi wire is for 309 stainless steel. It has a higher silicon content than ER309L wire, so it flows more easily when melted and fills in more of the space between the two pieces of your weld. It’s also better where appearance matters because it creates smoother welds.

ER316L wire is for 316 and 316L stainless steel.

ER316LSi wire is for 316 stainless steel. It has a higher silicon content than ER316L wire, so it flows more easily when melted and fills in more of the space between the two pieces of your weld. It’s also better where appearance matters because it creates smoother welds.

ER347 wire is for 321 and 347 stainless steel. It contains niobium, which reduces the chances of corrosion forming in your weld during the welding process.

Pair this wire with an MIG gun to fuse aluminum pieces together.

ER1100 wire is for 1100, 3003, and 5005 aluminum. Soft and easy to form, it’s often used to weld thin-gauge aluminum and foil. It also resists chemicals and corrosion. Anodize this wire to create a bright finish.

ER4043 and ER4047 wire is for 43, 356, 3003, 3004, 5052, 6061, and 6063 aluminum. Choose ER4047 wire when leak-tight joints are a must, such as when welding very thin aluminum or products that will hold pressurized liquids or gases. It flows more easily when melted than ER4043, so it spreads out and fills in more of the space between two pieces of your weld before hardening. It also shrinks less as it cools, which means it’s less likely to distort your weld. This wire stands up to prolonged high heat. Once hardened, it produces a bright finish with little soot.

This wire creates 40% stronger welds than standard welding wire for aluminum.

ER5356 rods weld aluminum 5050, 5052, 5083, 5454, 5456, 5457, and 5458. They have excellent corrosion resistance to salt water.

Join copper, copper-silicon, and copper-zinc to themselves and to steel. This wire is also good for welding uncoated or galvanized steel sheets.

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.
