soldering copper wire to aluminum wire
What are the risks of soldering copper wire to aluminum wire? I just
had to repair a wire on my Chevy truck. The original wire was aluminum and I spliced a copper wire between two ends of the damaged wire. It seemed to take the solder well but I have reservations about the longevity of the fix. What are the implications of having done this? Am I looking a a problem down the road (pun intended) Dave |

Dave,
How sure are you that it's aluminum wire? Aluminum does *not* take solder easily, special flux and techniques are usually required. More likely the wire is tinned copper - "tinned" basically meaning it's coated with solder already, and ends up looking a lot like aluminum. Eric Law "Dave" wrote in message ...

You need a special very powerful flux to do it successfully. -- Brian Gregory. (In the UK) To email me remove the letter vee. |

Yes, there were times when Al wires were used, but they have not very
nice properties. Al is amorph at normal temperatures and when connected with screw pressure terminals, will 'flow away' making loose connictions. I woud recommend however also in this case a crimp connection with standard car installation parts and checking then later every year to see if the connection is still OK. BTW: is the whole car wired with this kind of wires and cables? |

Repair method was splice and crimp & pack with dielectric grease. |
