Maybe they say bronze for simplicity. Suggesting the alloy contains some part of tin.
Basically brass is copper/zinc. Bronze is copper/tin.
But if you examine the mechanical properties of common copper alloys, you find perhaps a good dozen or more varieties.
All with different percentages of metals.
Nominal compositions of cartridge brass is 70/30 copper/zinc.
Naval brass is copper/zinc/tin.
Gunmetal varies with copper/zinc/tin + other elements.
Who can say with exactness just what was in the melting pot?
