Bronze is considerably less brittle than iron. Typically bronze only oxidizes superficially; once a copper oxide (eventually becoming copper carbonate) layer is formed, the underlying metal is protected from further corrosion. However, if copper chlorides are formed, a corrosion-mode called “bronze disease” will eventually completely destroy it.[11] Copper-based alloys have lower melting points than steel [...]

The discovery of bronze enabled people to create metal objects which were better than was previously possible. Tools, weapons, armor, and various building materials, like decorative tiles, made of bronze were harder and more durable than their stone and copper (“Chalcolithic”) predecessors. Initially bronze was made out of copper and arsenic to form arsenic bronze. [...]

Bronze was especially suitable for use in boat and ship fittings prior to the wide employment of stainless steel owing to its combination of toughness and resistance to salt water corrosion. Bronze is still commonly used in ship propellers and submerged bearings. In the twentieth century, silicon was introduced as the primary alloying element, creating [...]
