Tom--

Others can help, but I think the color on the two alloys is different.

The aluminum has more of a whitish silver color when polished, and tending toward dull sheen and sometimes gray when it gets a bit of tarnish.

Nickle silver has more of a yellow color to it because of the copper in it, and tarnishes yellow so at times it looks like brass.

Also, nickel silver is heavier.
