Pure Copper Mesh Red Copper Brass Phosphor Bronze Tinned Woven Mesh
Bronze is an alloy mainly composed of copper. Therefore, bronze wire mesh and copper wire mesh have many of the same characteristics, like malleability, durability, and ductility. The chemical composition of commonly used commercial bronze wire mesh is 90% Copper and 10% Zinc.
Bronze woven wire mesh has stronger corrosion resistance and durability than brass wire mesh. And it has a unique antique brownish-red color, which is an important reason for the use of bronze wire mesh from various marine and military applications to a commercial and residential insect screen. Bronze wire mesh is not as flexible and ductile as copper woven wire mesh for industrial needs, so it is often used in filtration and separation applications.
Brass is another copper alloy made of copper and zinc. And like copper wire mesh, brass wire mesh is soft and malleable. But its corrosion resistance is not as good as bronze.
As a wire mesh, the most commonly available brass woven wire mesh is referred to as “270 yellow brass” and has a chemical composition of approximately 65% copper, 35% zinc. “260 high brass”, which consists of 70% copper and 30% zinc is also popular in the mesh industry, particularly on custom manufactured items.
Zinc plays an important role in brass wire mesh, it increases the wear resistance and higher tensile strength of brass wire mesh. 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. 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 architectural, decorative and even artistic applications. Like virtually all wire mesh and wire cloth, brass wire mesh is used in architectural, decorative and industrial applications.
