Monel Alloys (Nickel-Copper Series)

Monel Alloys: Exceptional Strength in Corrosive Aqueous Environments. High-performance nickel-copper solutions for marine and chemical processing.

Monel

Monel alloys are characterized by their remarkable resistance to sea water, hydrofluoric acid, sulfuric acid, and alkalies. At Progressive Metal Manufacturing, we supply these alloys—primarily Monel 400 and Monel K-500—for applications where standard stainless steels succumb to stress corrosion cracking and pitting.

Technical Advantages

Marine Superiority: Virtually immune to chloride-ion stress corrosion cracking;

ideal for stagnant or flowing sea water.
Thermal Range: Maintains excellent mechanical properties from sub-zero temperatures up to $480^\circ\text{C}$.

K-500 Precipitation Hardening: Offers the same corrosion resistance as Monel 400 but with three times the yield strength through added Aluminum and Titanium.

Performance Metrics

Acid Resistance: Highly resistant to rapidly flowing brackish water or ocean currents.
Non-Magnetic: Monel K-500 is non-magnetic even at quite low temperatures, essential for electronic shielding.
Workability: Excellent weldability and grain structure for heavy-duty fabrication.

Applications

Marine propeller shafts, pump impellers, oil-well drilling tools (K-500), chemical plant valves, and heat exchangers.
