Monel, Copper Nickel Mesh

Heanjia Super Metals Co., Ltd. supplies Monel Mesh, it mainly include Monel 400 Mesh, Monel K500 Mesh and Copper Nickel alloy Mesh (Cu70Ni30/Cu90Ni10). The product forms include woven screen, perforated metal, expanded metal and sintered mesh.

Monel mesh is a premium nickel-copper alloy (primarily Ni 63-70%, Cu 27-34%) wire mesh known for exceptional corrosion resistance, high strength, and durability in extreme environments. It outperforms stainless steel in many aggressive chemical and marine applications.

Copper-nickel (Cu-Ni) alloy mesh is a highly corrosion-resistant, durable, and thermally conductive wire mesh used in marine, chemical, and industrial applications. The most common grades are 90/10 (C70600) and 70/30 (C71500), with excellent resistance to seawater, biofouling, and acidic environments. 

 🔹 Key Mesh Grades comparison:

Grade Composition Key Properties Best For
Monel 400 mesh (UNS N04400) 63-70% Ni, 27-34% Cu + Fe/Mn Excellent corrosion resistance marine & chemical industries
Monel K500 Mesh (UNS N05500) Ni-Cu + Al/Ti (precipitation-hardened) Excellent corrosion resistance,  Higher strength aerospace & deep-sea applications
90/10 Cu-Ni Mesh (C70600) 90% Cu, 10% Ni, <1% Fe/Mn Superior seawater corrosion resistance, good weldability Marine, desalination, condensers
70/30 Cu-Ni Mesh (C71500) 70% Cu, 30% Ni, <1% Fe/Mn Superior strength, higher corrosion resistance than 90/10 Offshore oil & gas, chemical processing
66/30/2/2 Cu-Ni (C71640) 66% Cu, 30% Ni, 2% Fe, 2% Mn Enhanced erosion resistance High-flow seawater systems

🔹 Key Properties & Advantages:

Monel 400 and K500: Excellent Corrosion Resistance

  • Resists seawater, sulfuric/hydrochloric acid, alkalis, and hydrofluoric acid (better than stainless steel).
  • Immune to chloride stress corrosion cracking (SCC).
    ✔ High Strength & Toughness
  • Retains strength at cryogenic to 550°C temperatures.
  • Monel K500 has twice the yield strength of Monel 400.
    ✔ Excellent Fabrication Properties
  • Can be welded, brazed, and soldered easily.
    ✔ Biofouling & Erosion Resistance
  • Ideal for marine filters, offshore platforms, and desalination plants.

Copper Nickel Alloy: Cu90/Ni10, Cu70/Ni30:

✔ Superior Corrosion Resistance 

   – Resists seawater, sulfuric acid, chloride, and biofouling (better than stainless steel in some marine environments). 

✔ Excellent Thermal Conductivity 

   – Used in heat exchangers, condensers, and HVAC systems. 

✔ Antimicrobial & Biofouling Resistance 

   – Copper ions inhibit algae/bacterial growth (ideal for marine and medical filters). 

✔ Good Weldability & Formability 

   – Easily fabricated into custom mesh shapes. 

✔ High Ductility & Fatigue Resistance 

   – Performs well in vibrating or high-stress environments. 

 🔹 Common Weave Types & Specifications 

  1. Plain Weave (Most Common)

   – Balanced grid for filtration, sieving, and shielding. 

   – Mesh Sizes: 0.2 to 200 mesh. 

   – Wire Diameters: 0.05mm to 5mm. 

  1. Twilled Weave

   – Stronger, denser weave for high-pressure filtration. 

  1. Dutch Weave (Micron-Level Filtration)

   – Fine mesh for filtering small particles in corrosive liquids. 

  1. Welded Mesh (Structural Use)

   – Used in marine grates, architectural facades, and industrial screens. 

 🔹 Top Applications 

 ✅ Marine & Offshore 

   – Seawater intake screens, boat hulls, desalination plants (resists biofouling). 

   – Offshore oil rigs (resists sulfide corrosion). 

 ✅ Chemical & Petrochemical 

   – Acid filtration, refinery screens, heat exchangers. 

 ✅ Power & HVAC 

   – Condenser tubes, cooling water systems. 

 ✅ Medical & Food Processing 

   – Antimicrobial filters, hygienic processing screens. 

 ✅ Architectural & Decorative 

   – Anti-corrosive facades, artistic mesh panels.
