H65 brass wire mesh ( C270 brass wire mesh) is the most extensively used brass alloy in the industrial wire cloth world. As its common industry name suggests, H65 brass is comprised of 65% copper and 35% zinc, with small additions of lead (0.045%) and iron (0.035%). When compared to copper wire cloth, C270 brass wire cloth possesses much better abrasion resistance, hardness, and tensile strength; it also exhibits improved corrosion resistance and lower electrical conductivity. As a higher zinc content results in a stronger, more ductile brass material, H65 brass is stronger and more ductile than 80-20 low brass and 70-30 cartridge brass, but weaker and less ductile than 60-40 muntz brass. In comparison to phosphor bronzes, C270 brass is a softer material
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, and 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.
Features & Use:
Superior to copper abrasion resistance and tensile strength.
60-70% copper plus 30-40% zinc.
Easily cut with hand tools.
It can be soldered with lead or silver solder.
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.
