That's interesting... I must've missed this earlier...
A while back, there were issues with using aluminum along with other metals in automotive and electrical applications.
Problems occurred with mating aluminum heads to cast iron engine blocks, as the two metals expand and contract at quite different rates. The problems were mitigated by use of titanium head bolts and the appropriate gasket materials.
During a copper shortage in the 70's, aluminum electrical wiring was used in some new construction, and problems occurred with connections to switch, receptacle, and copper wiring. A kind of electrolysis-induced corrosion occurred, and there were fires. While older aluminum wiring in good condition can be made safe by using the appropriate AL/CU connectors and anti oxidant grease at all connections, it is no longer code for most building.
That's all I know...
I doubt you'll have any problems with your application.
P.S. Per your avatar--I love that movie!
