Solder Copper Wire To Aluminum Sheet

If torch use is not feasible in your work space try a 150 watt soldering iron.

Solder copper wire to aluminum sheet.

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. 1280 can also be utilized in joining aluminum to difficult to solder metals like stainless steel nickel and kovar. How to solder aluminum with soldering iron. Then carefully run the soldering iron along the wire.

Drag the wire or rod of iron solder over the join while you indirectly continue heating the area i e. Typically a low temperature torch is used with a flame tip that reaches 600 to 800ºf 315 425ºc. Also make sure that the flux bubbles but not burn. Heat the solder enough so that it is melted evenly along the joint being soldered.

Once the flux is applied you can place the silver sheet on top of the copper sheet ensuring that the solder is face down on the copper sheet. Make sure the area that is covered is roughly the same as the size of your silver sheet. Use constant slow movements when applying the iron solder so that the outcomes can be even. Place your silver sheet to one side and apply a small amount of flux to the top side of your copper sheet.

You can use a soldering iron for joining aluminum wire but other jobs will require the use of a torch. Heating from the other side of the aluminum metal. Post solder residues are water soluble and should be cleaned post soldering. Make sure that the soldering iron touches both the aluminum wire and joint.

Wrap the wire around the area to be soldered.
