Brass: A copper alloy primarily composed of zinc, known for its attractive yellow color, collectively referred to as brass. The copper-zinc binary alloy is commonly known as ordinary brass or simple brass.

Special Brass: Brass with more than three elements is referred to as special brass or complex brass.

Brass Shell (C70 brass): Copper alloys with zinc content below 36% consist of solid solutions and exhibit excellent cold working properties. For instance, brass with 30% zinc is commonly used for making shell casings, known as brass shell or 73 brass. 64 Brass: Copper alloys with zinc content ranging from 36% to 42% consist of solid solutions, with 40% zinc 64 brass being a popular choice.

Copper-Helicopter Condenser Tubes (and other corrosion-resistant parts): To enhance the properties of ordinary copper, elements such as aluminum, nickel, manganese, tin, silicon, and lead are often added. Aluminum can increase the strength, hardness, and corrosion resistance of copper, but it reduces its plasticity, making it suitable for condenser tubes on helicopters and other corrosion-resistant components.

Naval Brass: Tin enhances the strength and corrosion resistance of brass against seawater, hence the name "Naval Brass," which is used for ship's thermal equipment and propellers.

Copper-Zinc Alloys - Watch Parts: Lead enhances the machinability of brass; this free-cutting brass is commonly used for watch parts.

Copper Castings: Often used for making valves and pipe fittings, etc.
