Brass and bronze are both metal alloys with copper as their primary component, but they differ in their composition, properties, and applications due to the additional metals mixed with copper. Here are the key differences between brass and bronze:

Brass:
- Composition:
- Brass is primarily composed of copper (Cu) and zinc (Zn). The proportion of copper to zinc can vary, resulting in different types of brass alloys.
- Color:
- Brass typically has a yellow-gold color, resembling the appearance of gold. The exact color may vary based on the zinc content.
- Properties:
- Brass is known for its malleability, ductility, and corrosion resistance. It has good electrical conductivity and is often used for decorative purposes, musical instruments, plumbing fittings, and electrical connectors.
- Applications:
- Common applications of brass include musical instruments (trumpets, saxophones), plumbing fixtures, decorative items, ammunition casings, and electrical connectors.
- Common Types:
- Different types of brass alloys include red brass (higher copper content, reddish color), yellow brass (balanced copper and zinc), and naval brass (copper, zinc, and a small amount of tin).
Bronze:
- Composition:
- Bronze is primarily composed of copper (Cu) with the addition of other metals, most commonly tin (Sn). Other elements, such as aluminum, silicon, or phosphorus, may also be present in varying amounts.
- Color:
- Bronze has a reddish-brown or tan color, which can vary depending on the specific alloy and the presence of other elements.
- Properties:
- Bronze is known for its strength, hardness, and corrosion resistance. It has good wear resistance, making it suitable for applications such as bearings, gears, sculptures, and architectural elements.
- Applications:
- Bronze is widely used in applications requiring durability and resistance to wear. Common uses include sculptures, bearings, bushings, marine components, and musical instruments (such as cymbals).
- Common Types:
- Various types of bronze alloys exist, including aluminum bronze (copper, aluminum, and sometimes iron), phosphor bronze (copper, tin, and phosphorus), and silicon bronze (copper, silicon, and small amounts of manganese, tin, or zinc).
