As copper wire soldered to aluminum without special flux for a few minutes

Metal aluminum is unique. It is very light, does not rust, even with very long contact with water. Its application is very widely used in various industries, so without it anywhere.

But here is soldered to ordinary copper wire of aluminum is not so easy as it seems at first glance. The thing is that the molten solder does not stick to this metal from -last its peculiar chemical properties.

Aluminum oxide coated film. which prevents lasting and better connection. Many are used for this purpose special funds in the form of flux. But as a rule proper result you get.

To succeed, you need to remove the protective film. Do it by mechanical means practically impossible, since the metal is oxidized and immediately covered with a new oxide.

Yet there is a way out of it and unfortunately not everyone knows. I remember the first time a way to read in one of the Soviet scientific - technical journals under the name "Radio"

What do we need for a good result:

Soldering iron 60 W

Solder

Motor oil

To begin, warm up the soldering iron. Then drip in a piece of aluminum and a few drops of oil to the place touch hot tip, simultaneously adding solder, then it is necessary to wait for at least one minute. It is necessary to place soldering properly warmed and the oxide film is collapsed.

Next you need a soldering iron to drive back and forth on the future site of contact and after a while you will notice that the solder grips with aluminum surface and remains a matter of technique.

Ludim copper wire and solder to the plate.

The entire chip is the use of oil - it protects the aluminum surface from oxygen, so oxidation does not take place and solder fine seizes the data metal.

A friend of mine told me that before, and all of this was used for normal sunflower oil. Of course, I have not tried it, but I think in the near future will hold such an experiment.
