Repair cracked metal in minutes with a flame—no welding machine, no mess, just a rod that melts and flows into the gap to form a durable bond.
SteelSwift bonds copper, aluminum, stainless steel, and iron using only heat from a flame you already own. Heat the rod until it liquefies, apply it to the crack, and as it cools it hardens into a hard, waterproof joint.
Pocket-sized and portable, these rods let you fix metal right at the break point—no bulky welding gear to haul or complex setup to learn.
How it works: the alloy melts at a low temperature, so a common flame is enough to get it flowing. Hold the flame to the rod, let the molten metal flow onto the damaged area, and it fuses to copper, aluminum, stainless steel, or iron with no flux required. As it cools, you’re left with a dense, sealed weld that resists heat, water, oil, and rust.
Step-by-step use in three simple steps
- Step 1: Hold a lighter, candle, or small torch to the rod until it starts to melt. No machine, no setup.
- Step 2: Let the molten metal drip onto the damaged spot and watch it fill the crack, fusing to copper, aluminum, stainless steel, or iron—no flux needed.
- Step 3: Let it cool to form a hard, waterproof bond that holds through use.
Pack options include sets of 3, 6, 8, or 16 rods. The composition is a copper-aluminum alloy designed to melt and flow with a low flame, suitable for copper, aluminum, stainless steel, and iron. It heats with a lighter, candle, or small torch and contains no flux or additives.
