MONEL® 400 Wire Mesh – Alloy Overview

Monel 400 wire mesh (aka Alloy 400) is a nickel-copper alloy that demonstrates good resistance in a wide variety of corrosive environments. Its nominal composition of ~67% nickel and ~31% copper traces its roots back to the early 1900’s when it was first developed by the International Nickel Company in an effort to use the high-copper-content nickel ore found in its Ontario, Canada mines. Alloy 400 wire cloth has excellent durability and strength following weaving, making it well suited for use in many industrial and commercial applications. In comparison to copper alloys, Monel 400 wire cloth is more resistant to oxidizing conditions. Versus Nickel 200, Alloy 400 wire mesh has greater resistance in reducing environments. As its color and appearance nearly match that of stainless steal, given Monel 400’s higher price point, it is not an alloy of choice for decorative applications. Some characteristics of Monel 400 wire cloth which dictate its wide use are:

  • Solid solution nickel-copper alloy.
  • At or below room temperature, it is somewhat-magnetic when annealed.
  • Above room temperature, it is non-magnetic (depending on composition impurities) when annealed.
  • Withstands outdoor exposure without rusting; great for use in marine and seawater settings.
  • Excellent corrosion resistance in broad range of industrial and chemical settings.
  • Good for use in hydrochloric acid; great for use against pitting & crevice corrosion in chlorides.
  • Excellent for use against chloride stress corrosion cracking.
  • Not to be used in phosphoric or nitric acid.
  • Max operating temperature of ~1000°F.
  • Can be cut, formed, and welded.
