Brass tube a free machining brass, is produced from a combination of copper and zinc, has the highest machinability of all copper alloys, and is the standard against which all the others are compared to. Brass tube, known for it\’s strength and resistance to corrosion with properties closely resembling that of steel, is one of the most popular copper alloys used today. Brass tube can be precision machined easily. Although ductile in its softened state, brass tube is a strong material to work with and maintains its strength even under some of the most demanding conditions. Brass tube forms a thin protective patina, which, unlike steel and iron, will not rust when exposed to the atmosphere. Brass tube is also valued for its high polished finish.
