Brass woven wire mesh is comprised of copper and zinc. A chemical composition of 65% Copper - 35% Zinc (a.k.a., 270 Yellow Brass) is recognized as the standard for stocked wire mesh in the industry. 70% Copper – 30% Zinc (a.k.a., 260 High Brass) is typically reserved for custom manufacturing. The presence of zinc in brass wire mesh is important because it provides added abrasion resistance and allows for higher tensile strengths. Because brass mesh is primarily composed of copper, it maintains many of copper’s unique characteristics, namely softness, malleability and resistance to certain acids.

The popular specifications featured here in opening size from 1” to approximately 1/12” and typically represent some of the larger opening sizes commonly requested in brass wire mesh. 1” x 1” and ¾” x ¾” specifications usually require custom manufacturing and are commonly used in infill panels, room dividers and various decorative applications. Other specifications, like 2 x 2 Mesh, 4 x 4 Mesh and other standard or market grade specifications, are used in gutter guards, air vents and filtration applications.
