What's the difference between brass and copper?

We often see various types of copper bars, pipes and plates, so what's the difference between brass and copper?

Brass and copper are both metals that have similar properties and are commonly used in various applications. However, there are some differences between them:

Composition: Copper is a pure metal, meaning it is made up of only one element, which is copper itself (Cu). On the other hand, brass is an alloy, which means it is composed of a mixture of copper and zinc (CuZn). The proportion of copper and zinc can vary, resulting in different types of brass with varying properties.

Color: Copper is known for its reddish-brown color, which gives it a distinctive appearance. Brass, on the other hand, has a yellowish color that can resemble gold.

Strength: Generally, brass is stronger and harder than copper. The addition of zinc to copper in brass increases its durability and makes it more suitable for applications that require strength, such as plumbing fittings, musical instruments, and decorative hardware.

Corrosion resistance: Copper has excellent corrosion resistance and is often used in electrical applications and for plumbing pipes. Brass also has good corrosion resistance but may be more susceptible to tarnishing or discoloration over time.

Malleability: Copper is highly malleable, meaning it can be easily shaped or formed into various shapes. Brass is also malleable but to a lesser extent than copper.

Applications: Copper is commonly used in electrical wiring, plumbing systems, roofing, and industrial machinery. Brass is widely used in musical instruments, decorative items, fittings, valves, and sculptures.

Overall, the main difference between brass and copper lies in their composition, color, strength, and specific applications.
