Plated aluminum bus bars in breaker boxes

Just a very quick question. ARe the breaker boxes/load centers with "plated aluminum bus bars" safe to use with standard copper wires (input main and output load) or are these only for use with aluminum wiring? Not an electrician but that seems cheap and dangerous to me but that's what Square D is putting out there for indoor and outdoor service panels these days. Seems like one would want copper bus bars with copper wiring. To GE's credit theirs have copper buss bars. Am I just being an old fuddy duddy?

The Square D QO panels use plated copper bus bars. The lugs are also plated.
I'm not sure on the Square D Homeline panels.

Many of the cheaper panels have aluminum bus bars and have no issues. The connetions like the lugs are listed for use with both copper and aluminum.
