MONEL 400（UNSN04400） WIRE
Nickel-Copper Alloy for Seawater, Hydrofluoric Acid & Reducing Media Service
MONEL 400 wire (UNS N04400) combines corrosion resistance with good ductility for mesh, screen, springs, ties, and general marine/chemical service. It can be supplied annealed or cold-drawn in coils or spools to match forming and weaving requirements.
As a professional Chinese nickel-based alloy manufacturer, we supply MONEL 400 wire with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
Typical supply range (custom sizes and tolerances available upon request):
Item | Range / Options | Notes |
Diameter | 0.10 – 12.0 mm | Fine wire by drawing; larger sizes by request. |
Form | Coil / Spool | Cut lengths available by agreement. |
Coil/Spool weight | 5 – 500 kg | Packaging by request (plastic spool / wooden reel). |
Surface finish | Bright / Pickled | Clean surface for weaving and forming. |
Condition | Annealed / Cold-drawn | Define temper for springs/mesh applications. |
Packaging | Spool / Reel / Coil | Export-grade packing available. |
Delivery condition | Annealed (standard) | Annealed & bright for fine wire by request. |
Dimension definition: DIA × COIL / SPOOL.
• Excellent corrosion resistance in flowing seawater and brackish water
• Outstanding resistance to hydrofluoric acid (HF) across wide concentrations
• Good resistance to alkalis, neutral salts, and many reducing media
• Resistant to stress corrosion cracking in most fresh and industrial waters
• High strength and toughness; remains ductile at subzero temperatures
• Can be strengthened by cold working; good fabrication and weldability
