  • Aluminum PCB and PCB Coil?

    I was just reading about the use of aluminum for PCB's, after having read most of thePCB Coils thread, which I didn't want to restart as it was awhile ago since it was last posted and it was already a lengthly thread. So, being the kind and benevolent person I am, I thought I would share. I left out modest and humble, but thats ok.)

    This is the article I was reading:
    http://www.key-to-nonferrous.com/def...Article&NM=118

    Some quotes from the above page:
    "
    Magnet Conductors

    Magnet wire of aluminum is a relatively new product; it utilizes EC aluminum. Its cross-sectional area must be 1.6 times that of copper wire to achieve equal direct-current resistance. Although this is a disadvantage in coils where space is a major consideration, aluminum wire has several economic advantages that often outweigh space considerations."
    "Aluminum conductor weighs half as much as equivalent copper conductor."


    "Low mass simplifies dynamic balancing of rotary equipment. It also results in higher sensitivity and response in many coil applications, as in instruments and acoustical devices."



    "Magnet Strip. With the development of aluminum strip conductors during the last decade, a new concept in electromagnetic coil design and winding technique has been exploited. Strip conductor coils can be wound with higher space factors and less layer-to-layer insulation than coils wound with round wire. With proper selection of strip insulation and coil design, it is possible to produce an aluminum strip-wound coil having the same physical dimensions and electrical characteristics as a coil wound with round copper conductor. The finished aluminum coil may weigh only half as much as the equivalent copper wire coil. Perhaps the most significant advantage of the aluminum strip-wound coil is cost."



    Theres alot of interesting information on aluminum alloys here also:

    And a variety of related information here:

    Also on the topic of coil design and perhaps more in the hypothetical technical area, is a post of mine from early this morning, (my time). It's basically about some ideas I had for coil design, but I posted it in the Tech Forum due to the fact that it had as much to do with the electronics "inside the box", while thinking "outside the box". You can find it here:

    Thank you for your time, we will now resume our regularly sheduled programming.

      I found it a little different, considering it seems everyone uses copper for most everything electronic these days.

      You might find the assorted links I posted in General Electronics useful as well.

        As to that Aluminum, I also don't see any reason for using it. Copper is Definately better and easy to solder for good connections.

        Besides, the Amount of Weight difference in using Aluminum would be very small on a typical detector coil.
