Bronze
Bronze is an alloy primarily composed of copper and tin. However, it can also contain other elements like phosphorus, manganese, aluminum, or silicon. It typically has a dull-gold color, though this can vary depending on the specific composition. Density varies with composition, often ranging from 7.4-8.9 g/cm³. The melting point is generally lower than brass, typically ranging from 850-1000°C. Bronze is known for its hardness, strength, ductility, wear resistance, and corrosion resistance, particularly in marine environments. Common applications include bearings, bushings, sculptures, bells, marine hardware, and certain types of tools.
