How Do You Tell the Difference Between Brass and Bronze?

Click to Expand

Brass and bronze are two metals often used interchangeably, but they are not the same. Although both are copper alloys, they have different properties and are used for various purposes. Therefore, knowing the difference between these metals is crucial, especially when choosing the right material for a specific project.

This article will explore brass and bronze’s characteristics — composition, applications, and cost.


Brass and bronze are both copper alloys that have been used for various purposes for centuries. Brass is a yellow-colored metal that has been in use since ancient times for decorative and functional objects like jewelry, statues, and musical instruments. On the other hand, bronze is a reddish-brown metal developed in the Bronze Age.

The composition of brass and bronze is one of the most significant differences between the two metals. Brass is typically made up of copper and zinc, with the proportion of each metal varying depending on the desired properties of the alloy. Zinc is added to copper to make brass harder and more durable than pure copper while also giving it a bright yellow color similar to gold.

Meanwhile, Bronze usually has a higher copper content than brass, making up a larger proportion of the alloy than zinc does. The inclusion of more copper gives bronze a reddish-brown color and makes it stronger and harder than brass, with better resistance to corrosion and wear. Bronze may also contain other metals, such as aluminum, silicon, or manganese.


The applications of brass and bronze are often determined by their unique physical properties. Brass — with its bright yellow color — is commonly used for decorative items such as doorknobs, lighting fixtures, and hardware. In addition, its ability to be easily molded and shaped makes it an ideal material for creating intricate designs. It is also widely used to produce musical instruments, particularly trumpets, trombones, and saxophones.

Bronze is used for more heavy-duty applications due to its strength and durability. Its strength, hardness, and wear resistance make it an ideal material for bearings, bushings, and gears. These applications require materials that can withstand high stress and heavy loads while providing low friction and wear resistance.

This material is also commonly used for sculptures, statues, and monuments due to its beautiful reddish-brown color and ability to hold fine details. Its durability and resistance to corrosion also make it ideal for outdoor applications where it is exposed to the elements. In addition, bronze is used for historical and commemorative plaques and medals due to its association with high value and prestige.


This cost difference between brass and bronze is mainly due to their composition. Copper is the main alloying metal in bronze, which is what makes it more expensive than brass.

However, the cost of both metals can also depend on the market demand and availability. For example, if the price of copper — the base metal of both brass and bronze — increases, the cost of both alloys will also increase. As a result, their market price can be volatile and subject to fluctuation.
