What is Bronze, and How is it Made?

Have you ever wondered what Bronze is? It’s a metal alloy made of copper and zinc, but there’s more to it than that. There are two copper and zinc alloys, one brass and the other Bronze. While both have their own distinct purposes, Bronze has been used for centuries as a durable material with many applications. Read on to learn more about this fascinating alloy.

What is Bronze?

Bronze is an alloy of copper and zinc. It usually contains between 8%-10% zinc and 88%-90% copper. Copper makes up most of the alloy because it gives the metal its unique color, which can range from yellowish-red to yellowish-brown, depending on the amount of zinc in the mixture. Additionally, copper provides strength to Bronze, making it very resistant to corrosion and abrasion. The exact composition of bronze depends on its intended use; different alloys are used for different purposes. For example, brass—which shares many properties with bronze—is typically composed of copper and zinc, while bronze castings may contain tin or lead, and copper.

The most common type of Bronze used today is called phosphor bronze or tin bronze, which contains 1%–11% tin along with the other components listed above. Tin makes the alloy much stronger than pure copper while also improving its resistance to wear and tear over time due to its high melting point (1250°C). This type of Bronze is often used for items such as coins, jewelry, sculptures, musical instruments, springs, bearings, valves, and connectors.

The process by which Bronze is created involves mixing molten copper with molten zinc in a furnace. As soon as these two metals come into contact with each other, they form an alloy that hardens upon cooling. Depending on the desired properties required for a specific application (e.g., hardness or ductility), other metals, such as aluminum or silicon, may be added during this process in order to achieve the desired outcome.

Bronze Composition

Bronze is an alloy composed primarily of copper and tin, along with traces of other metals such as zinc, nickel, aluminum, and silicon. The proportions of these elements determine the properties of bronze including strength, malleability, ductility, coloration and corrosion resistance. Bronze has been in use since ancient times as it is easy to shape into tools or items through casting or hammering-out techniques. It has also been used for decorative purposes due to its attractive metallic hue.

How Is Bronze Made?

Making a bronze is quite simple once the right ingredients have been selected. Copper ore must first be mined from the earth before being purified in a furnace to remove impurities such as sulfur and arsenic. Once purified, the copper ore can be melted into a liquid form. Other metals, such as tin or zinc, can then be added to achieve the desired composition before the molten metal is poured into molds for casting into its final shape. This process can be done manually or mechanically, depending on the required size and scale of production.


Bronze has been around for thousands of years and continues to be used today due to its impressive strength and durability compared to other metals like iron or steel. It’s an excellent choice for applications requiring corrosion resistance or wear resistance—such as coins and sculptures—and can even be formed into intricate shapes using casting techniques if needed! So next time you see something made out of Bronze, take a moment to appreciate just how special this metal is!
