Bronze is an alloy of copper and

Bronze is a metallic alloy primarily composed of copper and tin [2]. Historically, the addition of tin to copper marked the beginning of the Bronze Age around 3000 BCE, as it produced a material significantly harder and more durable than pure copper [1]. While modern bronze can sometimes include other elements like zinc, manganese, or aluminum to modify specific properties such as corrosion resistance or strength, tin remains the defining alloying element [3]. In contrast, brass is distinguished as an alloy of copper and zinc [3]. The combination of copper and tin typically results in a material with a reddish-brown color, high ductility, and a high melting point, making it historically essential for manufacturing tools, weapons, and intricate ornaments [2].
