In order to even think of making statements of this kind, one must know something of equilibrium phase diagrams and the thermal behavior of elements and their compounds and alloys. Do you?
Copper melts at 1084, tin at 230, but when brass melts at 930, you don’t get liquid tin with chunks of copper in it.
(1) Prove it, using the Cu-Sn binary phase diagram.
(2) What has this to do (even if it was true) with the behavior of compounds in a U/Al regime?
Respectfully ---
I’ve seen brass poured at a foundry.
