Brass, at its core, consists of copper combined with zinc. It possesses strength while also being easily moldable, stamped, or drawn, making it a prevalent option for a wide range of applications. By adjusting the quantity of zinc present, various attributes can be attained, such as differing degrees of corrosion resistance, ductility, and suitability for machining.
