Nickel-copper alloys

Your Trusted Source for Monel Alloy Manufacturing

Monel alloys are nickel-based alloys known for their exceptional corrosion resistance, high strength, and durability. These nickel-copper alloys typically contain about 67% nickel and 28-29% copper, along with small amounts of iron, manganese, and other elements to enhance their performance.

Available grades: Monel 400, Monel K500

Outstanding corrosion resistance in seawater, acidic environments, and other corrosive media
Maintains good mechanical properties even at low temperatures
Excellent resistance to chloride-induced corrosion, making it suitable for harsh marine environments
Retains its physical properties across a wide temperature range, including high and low temperatures
Easily forged, rolled, drawn, and processed into various shapes for different applications
Low magnetic permeability, making it ideal for magnetically sensitive applications

Marine engineering: Used in shipbuilding, subsea pipelines, and seawater desalination systems
Chemical & petrochemical industry: Applied in reactors, heat exchangers, pumps, and valves
Energy sector: Found in nuclear and thermal power plant cooling systems
Food processing & pharmaceuticals: Used in mixers, reactors, and food-handling equipment
Aerospace industry: Applied in aircraft engine components and spacecraft structures
Oil & gas extraction: Utilized in well piping and subsea production systems
Electronics & Battery Industry: Used in lithium battery connectors and sputtering targets
