    Phil,
    If copper and aluminum wires must be spliced together there are approved methods and materials that may be used. Smaller wire gauges such as #12 and #10 may be spliced together using CU/AL approved wire connectors where a anti-corrosion compound is used. Larger wire sizes may be spliced using a variety of lugs or terminals and anti-corrosion compound depending on the application. When installing aluminum conductors as service feeders or larger circuits where permitted, the bare wire portion of the aluminum conductors should be coated with an approved anti-corrosion compound and tightened to the proper torque specs.
    Aside from the concern of corrosion, another concern about using aluminum wire is that the metal is softer and when there is a load present the wire may become warm, which can produce expansion and contraction of the aluminum conductor. If the connection is not made well then the expansion and contraction can eventually create a loose or bad connection that could eventually create arcing which can produce a number of hazardous conditions.
    However when approved materials are used and approved methods are followed one will greatly reduce to possibility of a problem when using aluminum wiring where installing aluminum wiring is permitted.
    I hope this helps you.
    Dave
