Adding elements such as aluminum, silicon, manganese, lead, and tin to copper-zinc alloys forms special brasses, such as lead brass, tin brass, aluminum brass, silicon brass, manganese brass, etc.

Lead brass has excellent machinability and wear resistance, widely used in manufacturing clock parts, and for casting bearings and bushings.

Tin brass has good corrosion resistance and is widely used in manufacturing marine parts.

Aluminum in aluminum brass enhances the strength and hardness of brass and improves its corrosion resistance in the atmosphere. Aluminum brass is used for manufacturing corrosion-resistant parts.

Silicon in silicon brass improves the mechanical properties, wear resistance, and corrosion resistance of copper. Silicon brass is mainly used for manufacturing marine parts and chemical machinery components.
