That reel frame was cast by pouring molten metal into a mold.

There's no telling what the reel frame is made of but it is certainly an alloy of several to many metals. Typically, there would be a lot of zinc mixed with tin and copper, maybe with some lead or magnesium added too.   We used to call all such stuff "pot metal" which is sort of a derogatory term as it implies that the casting may be brittle and not very strong (as demonstrated here).  It's advantage is that it's inexpensive and light weight.

Some of us still call that sort of stuff "pot metal", and in the derogatory sense, too. At least there have been a few upgrades to the quality since the early days.
