The Differences Between Brass and Bronze



Brass and bronze are often marketed interchangeably, but they are far from the same material. Both
play a valuable role in modern manufacturing, but one is often more suitable for a particular application
than the other. To know which is best for your project, it is essential that you understand the differences
between the two. Here are the basic differences between brass and bronze.
History
Bronze is far older than brass, dating to the Sumerian people around 3500 BC. A far stronger and more
durable material than stone and copper, the discovery of bronze gave mankind the hallmarks of the
Bronze Age, including more detailed metal sculptures, new decorative tiles, and a wide range of new
tools, weapons, and armor.
Brass was discovered in approximately 500 BC. Its natural golden color and tarnish resistance made
brass useful for the production of coins and other items where a lustrous appearance was desired.
However, it was difficult in those days to create brass, so it was not until medieval times that brass
became a commonly used material for church monuments and wire. By the 17th century, brass was the
alloy of choice for instruments that required accuracy, such as clocks, navigational aids, and precision
scientific instruments.
Composition and Properties
Bronze is a metal alloy based on copper and tin. Other elements such as aluminum, silicon, phosphorus,
and manganese may also be added. It is brittle and hard, but resists corrosion and metal fatigue better
than steel. Bronze is a good conductor of both electricity and heat. Its color is reddish-brown.
Brass is a metal alloy based on copper and zinc. Iron, silicon, aluminum, and manganese may be added
to improve corrosion resistance. Brass is more malleable than either zinc or copper, and it has a relatively
low melting point of 900 C. Brass is not as hard as steel. It has the appearance of muted, dull gold.
Uses
Bronze is particularly useful in marine applications due to its corrosion resistance. It is frequently used
to create cast sculptures, and it is generally considered one of the best materials for creating bells and
cymbals. Industrial uses for bronze include bearings, springs, electrical connectors, and a variety of clips.

Brass is commonly used for decorative pieces, and it imparts excellent acoustic properties to a variety of
musical instruments. It is also common in applications that require low friction, such as valves, gears,
doorknobs, ammunition, and locks. It is not prone to sparking, so it is often used for zippers as well as
fittings and tools that will be used around explosive gases. Brass is also a popular choice for boat
hardware.
Both brass and bronze are in common use today. However, they are not the same material, and their
properties differ significantly. Make sure you choose the metal that is truly the best option for your project.
