Brass

C2600/ C2680/ C2801/ Others

Brass is a copper-zinc alloy metal with fine ductility and workability in punching processes. It is suitable for making precision instruments due to its excellent mechanical workability and wear-resistant performance. It is used to make parts of ships and vessels because of its corrosion-resistant nature. Its golden luster becomes sheer and bright after polishing, so it is utilized to bring out a sense of craftsmanship in products such as musical instruments and sanitary ware.

Brass: A fine look with excellent workability in punching processes.
