Cuivre-zinc, also known as brass, is an alloy primarily composed of copper and zinc. The proportions of these metals can vary, but brass typically contains 55-95% copper and the remainder zinc. This alloy is valued for its attractive golden-yellow color, high strength, and excellent corrosion resistance. Brass has been used for centuries in various applications, including musical instruments, plumbing, and decorative items.

The addition of zinc to copper enhances the alloy's strength and corrosion resistance. Zinc also improves the alloy's machinability and reduces its melting point compared to pure copper. Brass is also known for its excellent acoustic properties, making it a popular choice for musical instruments such as trumpets and trombones.

Brass is often classified based on its copper content. For example, yellow brass contains 60-70% copper, while red brass contains 70-85% copper. The higher the copper content, the harder and more resistant to corrosion the brass becomes. However, it also becomes more brittle and less malleable.

Brass is a versatile material that has been used in various industries for centuries. Its unique properties make it an essential material in many applications, from musical instruments to plumbing and decorative items. Despite its widespread use, brass is not without its drawbacks. It is more expensive than other metals and can be difficult to machine due to its hardness. Additionally, brass is not as strong as some other alloys, such as steel, and can be prone to corrosion in certain environments.
