I'm not 100% certain, but I think there's probably a good reason that bronze age weapons and tools were cast rather than forged. I recommend researching the topic of bronze age tools and how they were made.
I can only speak for ancient Mesopotamia, but there are several
points to remember on the topic of Bronze Age tools and weapons:
–the composition of bronze was never consistent, anywhere in the
Ancient Near East;
–bronze was used earliest and (for a time) most often for jewelry
and decorative and, most likely ritual, implements;
–there is no particular advantage to hot-forging bronze, and the
type of tongs needed to handle a hot ingot did not exist;
–in order to forge bronze, one would have to cast an ingot first,
so it’s not as if one could skip the casting stage. Lost-wax
casting was in use in the 4th millennium BC.
