Soldering Aluminium Wire To Copper

Soldering aluminium wire to copper. The 5000 series aluminum is hit or miss. If using a torch hold the torch tip at least 4 to 6 inches 10 2 to 15 2 cm away from the parent metal. Soldering involves melting a low temperature metal alloy over a joint or wire splice to secure 2 pieces together without the risk of them coming undone. You either need a very aggressive flux to strip the oxide not to mention damaging your soldering iron tip and the copper or some method of mechanically stripping the oxide layer and keeping oxygen away from it the layer re forms immediately until you have completed the joint.

Successfully soldering aluminium wire is hard. He is plating aluminium with copper and then soldering to copper. Do not apply too much solder as it may fill in other gaps and cause shorts. But when soldering aluminum to a more solder friendly metal like copper you re at an advantage.

Also keep in mind that it s always most challenging when soldering aluminum to aluminum. And then just solder wire inside the engine oil puddle. Use your torch or soldering iron to heat the metal object adjacent to the join starting at the lower end of the workpiece. Then carefully run the soldering iron along the wire.

When it can be soldered it can only be done so by first pre tinning the surface of the aluminum. Heat the solder enough so that it is melted evenly along the joint being soldered. Also make sure that the flux bubbles but not burn. If you want to combine 2 wires you can easily use solder to make a connection that will last for a long time.

Soldering to aluminum is very difficult and quite different than soldering to copper or solder coated surfaces. Multi sol mutli metal solder copper to aluminum fitting on an aluminum coil. A direct flame on the repair area is likely to overheat the solder and flux. Low temp 350 degrees with no worry about melting the aluminum or too much he.
