Square brass tubing is made from Alloy 272 or common brass, and it exhibits a yellow color. Its chemical composition is about 63% copper and 37% zinc. Of all the copper alloys, Alloy 272 has the highest machinability, meaning it can be easily shaped depending on its intended purpose. The material is also very resistant to corrosion.
These tubes are categorized by their nominal measurements, or the outside diameter. There are also varying thicknesses of the tube walls ranging from 0.02 inches to about 0.10 inches. Square brass tubing may be cut and used for fasteners in construction projects.
Other known uses of square brass tubing include ornamental work, hand rails, furniture and light fixtures, as well as circuit board components. Alloy 272, when used in tubing, is not heat treatable, and welding is not recommended. It can, however, be bent, sheared, or spun to create the shape needed.
Brass tubing, like all other brass components, can exhibit wear and tear over a period of time. When exposed to the air, the copper content of brass may form a salt layer, called a patina. This creates a greenish sheen on the surface of brass. Note that this is not an indication of corrosion or rust, but only a change in color of the metal.
If you’re in search of a particular grade of brass or a specific size of tubing for your project, talk to a trusted supplier for high quality metals. They can readily provide you with the materials you need, at the ideal rates you’re looking for.
