65-35 Yellow Brass Wire Mesh – Alloy Overview

65-35 yellow brass wire mesh (aka C270 brass wire mesh) is the most extensively used brass alloy in the industrial wire cloth world. As its common industry name suggests, 65-35 yellow 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, 65-35 yellow 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. Some characteristics of 65-35 yellow brass wire cloth which dictate its wide use are:

  • The most widely used brass alloy for cold-forming.
  • Non-magnetic in all forms.
  • Golden yellow in color.
  • Withstands outdoor exposure without rusting.
  • Corrodes when exposed to ammonia and other salts.
  • Good thermal and electrical conductivity.
  • Antimicrobial.
  • Can be cut, formed, and welded.
