AI overview

Brass is a metal alloy that has been used since ancient times to create both functional and decorative objects, as seen in historical items like Islamic Golden Age astrolabes and medieval European lecterns. It has mattered throughout history because its properties make it suitable for crafting precision instruments, religious objects, and other important items across different cultures and time periods.

Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic, and chemical properties, but copper typically has the larger proportion, generally copper and zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.
