Difference between Bronze and Brass
Bronze and brass have their own unique characteristics that set them apart from one another. While bronze is primarily made of copper, adding tin and other metals can change its composition to some extent. On the other hand, brass is mainly made of copper and zinc, but small quantities of other elements like lead can also be added to alter characteristics.
Here’s a breakdown of the essential differences between bronze and brass:
Bronze | Brass | |
Composition | Primarily copper with additions of tin, aluminum, silicon, nickel or zinc. | Primarily copper with additions of zinc and small amounts of other elements like lead. |
Melting Point | 950 – 1050°C (1742 – 1922°F) | 900 – 940°C (1652 – 1724°F) |
Density | Denser than brass. | The less dense of the two metals. |
Tensile strength | Bronzes are harder and stronger than plain copper because they include alloy elements such as tin which strengthens the alloy matrix. The red-brass series offers higher levels of corrosion resistance than the yellow-brass series. | The higher percentage compositions for sensitive applications often contain lead to enhance machinability. |
Color/tone/finish | It tends to have a bolder, tighter molecular structure that is well-suited for casting. | Shades of golden-yellow when polished but has also been known to take on shades of greys, blacks or greens depending on the environment and patina. |
Uses | Bronze is used in making sculptures, monuments, musical instruments, bearings among other industrial applications. | Brass is used in musical instruments primarily because it has bright tones. Industrial applications often favor brass due to its high durability and strength. |
A significant difference between bronze and brass is their composition. The admixture of tin makes bronze more robust compared to pure copper which provides better hardness for industrial use as well as sculpting benefits. Brass contains zinc rather than tin, giving it different properties such as being less dense than bronze while packing lighter weight with a lower melting point.
However, these two copper alloys tend to form similar patterns when exposed to the air around them over time. Patina’s effect changes each slightly different color shades making it difficult at times to distinguish without precise identification qualities.
