Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of two or more elements, it is called special brass. Brass has strong wear resistance, and brass is often used to manufacture valves, water pipes, connecting pipes for internal and external air conditioners, and radiators. The term brass refers specifically to copper-zinc alloys, which began in the Ming Dynasty, and its records are found in the “Ming Hui Dian”: “In Jiajing, there are 6 million coins in Tongbao, and 47,270 in two-fire brass. Two jin…” Through the analysis of the composition of copper coins in the Ming Dynasty, it was found that the copper in the real sense of the money-casting species mentioned in “Ming Hui Dian” appeared much later than other copper alloys. It is difficult to obtain metallic zinc.
Zinc oxide can be quickly reduced to metallic zinc at a high temperature of 950°C-1000°C, while liquid zinc has already boiled at 906°C, so the reduced metallic zinc exists in the form of vapor. The reaction is reversed during cooling, and the vapor zinc is oxidized to zinc oxide by carbon dioxide in the furnace, so a special condensing device is necessary to obtain metallic zinc. This is why the metal zinc was used much later than copper, lead, tin, and iron, and one of the reasons why brass coinage appeared later.
Ordinary brass is a copper-zinc binary alloy, and its zinc content varies widely, so its room temperature structure is also very different. According to the Cu-Zn binary state diagram, there are three types of brass at room temperature: brass with a zinc content of less than 35%, the microstructure at room temperature is composed of a single-phase α solid solution, called α brass; zinc-containing Brass with an amount in the range of 36% to 46%, the microstructure at room temperature is composed of (α+β) two-phase, called (α+β) brass (two-phase brass); the zinc content exceeds 46 %~50% of brass,
