Zamac 2 runs about 52,000 PSI. Steel is stronger, but not by that much
until you get to better grades. For example, 1144 runs about 100,000
PSI, which is MUCH stronger.
While C932 bearing bronze is 20,000 PSI, C863 is 66,700 PSI.
So, while zinc alloys are close to mild steel (my initial assertion),
other grades of steel and some bronzes are MUCH stronger (which supports
your assertion from your experience in heavy machinery.)
