70-30 Cartridge Brass Wire Mesh – Alloy Overview

70-30 cartridge brass wire mesh (aka C260 brass wire mesh) is one of the most used brass alloys in the industrial wire cloth world. As its common industry name suggests, 70-30 cartridge brass is comprised of 70% copper and 30% zinc, with small additions of lead (0.035%) and iron (0.025%). When compared to copper wire cloth, C260 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, 70-30 cartridge brass is stronger and more ductile than 80-20 low brass, but weaker and less ductile than 65-35 yellow brass and 60-40 muntz brass. In comparison to phosphor bronzes, C260 brass is a softer material. Some characteristics of 70-30 cartridge brass wire cloth which dictate its use are:

  • One of the most used brass wire cloth alloys (65-35 yellow brass being the most used).
  • 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.
