Classification of brass; if brass materials consist of more than two elements and are multi-alloys, they are called special brass. For example, copper alloys composed of lead, tin, manganese, nickel, iron, and silicon. Brass has strong wear resistance. Special brass, also known as specialty brass, features high strength, high hardness, and strong chemical corrosion resistance. Its mechanical properties for cutting operations are also notable. Seamless copper pipes made from brass are soft and have excellent wear resistance. These seamless brass pipes can be used in heat exchangers and condensers, low-temperature pipelines, and submarine transport pipes. They are also used to manufacture plates, strips, bars, pipes, and cast parts. With a copper content of 62%–68%, they have good plasticity and can be used to make pressure-resistant equipment.

Properties of brass; Brass is an alloy of copper and zinc. The simplest form of brass is a binary alloy of copper and zinc, known as simple brass or ordinary brass. By varying the zinc content in brass, brasses with different mechanical properties can be produced. The higher the zinc content in brass, the greater its strength but the slightly lower its ductility. In industry, brass containing no more than 45% zinc is used, as higher zinc levels can cause brittleness and degrade the alloy's performance. To enhance certain properties of brass, brasses made by adding other alloying elements to monomeric brass are called special brasses. Common alloying elements include silicon, aluminum, tin, lead, manganese, iron, and nickel. Adding aluminum to brass increases its yield strength and corrosion resistance while slightly reducing ductility. Brasses with less than 4% aluminum have excellent comprehensive properties for processing and casting. Adding 1% tin to brass significantly improves its resistance to seawater and marine atmospheric corrosion, hence it is called "naval brass." Tin also enhances the machinability of brass. The main purpose of adding lead to brass is to improve machinability and wear resistance; lead has little effect on the strength of brass. Manganese brass possesses good mechanical properties, thermal stability, and corrosion resistance; adding aluminum to manganese brass further improves its performance, resulting in castings with a smooth surface. Brass can be divided into two categories: cast products and processed products via pressure treatment.
