Key Differences

Bronze and iron are both materials that have played pivotal roles in the progression of human civilization. Bronze is an alloy which means it's composed of two or more elements. Typically, it's a mixture of copper and tin. Its characteristic brownish-yellow hue and resistance to corrosion made it a favored material in ancient times for tools, weapons, and art.
In contrast, iron is a singular element on the periodic table. It is grayish-white and has been central to various technological advances due to its strength and abundance. However, unlike bronze, iron is susceptible to oxidation which results in rust. When exposed to moisture, iron can degrade, making protection and maintenance crucial.
Bronze artifacts indicate ancient civilizations' advancement into the Bronze Age, a period marked by the utilization of this alloy. This age was eventually succeeded by the Iron Age, when methods to smelt and utilize iron became widespread. The Iron Age saw a significant increase in tools and weapons' durability due to iron's inherent strength compared to bronze.
Another distinction between bronze and iron pertains to their uses in contemporary times. Bronze is often associated with medals, sculptures, and some musical instruments due to its tonal properties and aesthetic appeal. Iron, with its strength and magnetic properties, has found widespread use in construction, transportation, and even in the cores of planets due to its abundant nature.

Iron

The most common and most useful metallic element, being of almost universal occurrence, usually in the form of an oxide (as hematite, magnetite, etc.), or a hydrous oxide (as limonite, turgite, etc.). It is reduced on an enormous scale in three principal forms; viz., cast iron, steel, and wrought iron. Iron usually appears dark brown, from oxidation or impurity, but when pure, or on a fresh surface, is a gray or white metal. It is easily oxidized (rusted) by moisture, and is attacked by many corrosive agents. Symbol Fe (Latin Ferrum). Atomic number 26, atomic weight 55.847. Specific gravity, pure iron, 7.86; cast iron, 7.1. In magnetic properties, it is superior to all other substances.
