Visually how can you tell the difference?
years ago i had taken some "brass"to a machinest and he told me it was bronze.
I will scrounge odds and ends here and there
and have noticed that some pieces look yellow and some have a reddish tinge.
is there any way to harden or anneal either of these?
Thanks.

There is no such thing as "good enough", either your work is good or it is not. How is your work?

The rule of thumb is that reddish or pinkish tinged material is bronze and the yellowish is brass. There are two exceptions, red brass which is reddish and very soft and commercial bronze which is yellowish and hard. All can be annealed in a propane flame, NEVER acetylene. All will work harden a bit.

Phosphor bronze, aluminum bronze, and berrylium copper are the tough ones.

Stay away from engravers brass it is the worst material I have had the pleasure of drilling, extremely sticky.

I've read that certain alloys will actually harden. Such as the Aluminum Bronze. It's said the Aluminum will act much like the carbon in steel thus making it hardenable. I've never confirmed this so...

George why can't acetylene be used?
I spent 35 years in machine shops and never heard of this before and am now wondering if some possibley unsafe practices may have been done?

TIA.
