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
- Plain Weave (Most Common)
