Brass can be used for wire mesh. It is an alloy that is comprised of copper and zinc, and, like copper, brass is soft and malleable and is attacked by ammonia and related salts. As a wire mesh, the most commonly available brass woven wire mesh is known, in certain circles, as “270 yellow brass”, which has a chemical composition of approximately 65% copper, 35% zinc. “260 high brass”, which is a 70% copper, 30% zinc is also a popular in the mesh industry, particularly on custom manufactured items.
The presence of zinc in brass woven wire mesh is important as it provides added abrasion resistance and higher tensile strengths; it also hardens the mesh, compared to its softer copper woven wire mesh counterpart. For these reasons, brass wire mesh is commonly used in filtration and separation applications, and it is used to fabricate discs, especially when electrical conductivity is not critical.
In most cases, industrial grade brass woven wire mesh has a golden yellow color to it, and this unique color makes it appealing for use in decorative and even artistic applications.
