Bronze vs Iron

Iron displaced Bronze, and 3 measured properties show why — density most clearly.

Bronze vs Iron

These are different kinds of thing (alloy, element). Fewer properties mean the same thing across both, so a like-for-like reading may not be available.

Bronze

Copper alloyed with tin — harder than either constituent, and the first engineered material to define an age.

Iron

Fe

The most-used metal on Earth by a wide margin, and the element that ended the Bronze Age.
