What would be the differences between an engraved bronze plaque and an engraved aluminum plaque, besides color?

If you're talking about engraved plaque....
Bronze: heavier (3 times aluminum), and will feel more valuable. Look at plaques and statues in some old cities - they look old and antique over time but still last for a long time.
Aluminum: lighter and not as expensive-looking. It is also softer, so scratches easier. But if you want more modern look it is good. You can even get different colors by "anodizing": gold, champagne, purple, etc. - if your maker offers them.

Bronze is an alloy of copper and tin. Aluminum is an element. One is gold color and the other is silver.

Your bronze plaque would weigh more (if same size) and it would tarnish over time.

Bronze is an alloy of tin and copper and tends to begocome brittle in cold weather. It also will tarnish over time, turning green.
Alluminum is lighter and will not corrode.

Bronze is stronger and sturdier. not to mention alluminum is very expensive, and although it is the most common element in earth's crust, refining it is very expensive, and is only profitable is a few places such as austrailia. ever wonder about the true motive of recycling? it is cheaper to recycle alluminum than to mine more. it has nothing to do with nature, only profit
