Bronze alloy

Definition

A bronze alloy is a metal mixture primarily composed of copper and tin, often used for casting and metalworking. This alloy has been favored throughout history due to its durability and resistance to corrosion, making it ideal for producing various objects like statues, coins, and tools. The unique properties of bronze alloys have led to their widespread use in art and industry, particularly in ancient civilizations where metalworking techniques were advancing.
