Brass, primarily comprised of copper alloyed with zinc, exhibits an attractive yellow appearance and is commonly known as brass. The simplest binary alloy of copper and zinc is referred to as ordinary brass or just brass. Brass alloys typically consist of zinc in the range of 36% to 42%, forming a solid solution, with brass containing around 40% zinc being the most frequently used composition. To enhance the performance of ordinary brass, other elements are often added. For instance, manganese is occasionally used as a deoxidant, and even in small quantities, it can have a grain-refining effect, further improving the alloy’s properties.
