    I only give back the savings of materials on these if it's my voluntary alternate.

    If it is requested, I will look at the labor, and maybe offer some of the savings back

    Aluminium but let that pass..................
    The answer is no. For control panel wiring, VFDs, installations, etc. I can't say it is never used but I don't recall any instances of it.

    The only places I've seen Al conductors used was the bus bars on high current rectifiers. I mean suites of 10kA and upwards.
    And on extruded heat sinks for power semiconductors.
