A 50# brass bell would sound like crap.
Good heavy bells are made of bronze. There's a very clear metallurgical reason why.
Small bells don't matter as much, but bronze bells are louder & have a longer, smoother decay.
It's way more complimentary to use bronze in that description.

...of bronze wind charms in our backyard. The longest chime is 2' long, so it's all low, warm tones.
Awesome when the wind blows.
As bells get bigger, the drop in surface to mass ratio changes their tone.
The tin in bronze helps stiffen the crystal matrix & it's size. That keeps the copper atoms from moving in random vibrations, so the energy is not as quickly dissipated.
Makes for a more full tone than brass.
Even aluminum can make a loud bell, but the decay is quick & brittle sounding.
That's why church bells & carillons are mostly cast from bronze.
Loud, penetrating, smooth & they last practically forever.
Unless of course, there's too much tin & carbon. Then you get what happened to the Liberty Bell.
Yeah, I know way too much about how bells are made!
