I'm no metallurgist so forgive my ignorance. Most of
us have had the problem of interfacing copper to
aluminum. Is there some sort of alloy terminal block
that will accomplish that feat? Seems simple enough
to create an alloy that gradually transitions from
copper to aluminum but what do I know?

1. I encountered dissimilar metal parts which had been joined by what was
termed "explosive welding" and/or "explosive bonding" both of which terms
show up nicely in Google.

In my case, the parts were cylindrical sleeves, the top of each being
stainless steel and the bottom being aluminum. I only saw one (out of
thousands) with the bond fractured and I don't know what hit it to break it.
They seem quite strong.

Perhaps a vendor of such products has something you can use.

2. I see a lot of brass and darn little corrosion. Would a transition
piece of brass be acceptable?
