Copper vs. Brass: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 22, 2023
Copper is a pure elemental metal with reddish-brown color, while brass is an alloy made primarily of copper and zinc.

Key Differences

Copper is a naturally occurring metal that has been utilized by humanity for thousands of years. Recognized for its reddish-brown color, copper is a good conductor of electricity and heat. On the other hand, brass, with its distinctive yellow hue, is not a pure element but an alloy composed primarily of copper and zinc.

Copper is versatile and can be found in electrical wires, plumbing pipes, and even in the human body as a vital mineral. It has antimicrobial properties, which make it useful in various medical and environmental applications. Brass, because of the addition of zinc, tends to have different properties than pure copper. This combination grants brass its unique characteristics, making it harder and more resistant to corrosion than copper.

The uses of both copper and brass are varied. While copper often finds applications in electrical circuits due to its conductivity, brass is more commonly used in decorative fixtures, musical instruments like trumpets, and in cartridge casings. The presence of zinc in brass makes it less electrically conductive compared to copper.

Another notable distinction between copper and brass is their malleability. Copper, being softer, can be bent and shaped with relative ease. Brass, although still malleable, is harder and might require more force to shape. Both materials, however, are ductile, allowing them to be drawn into wires.

The color difference between copper and brass can often be the most immediate and noticeable distinction for many. While copper boasts a reddish-brown shade, brass presents a more yellowish hue, due to the presence of zinc. Over time, both materials may tarnish or develop a patina, changing their original appearance.
