Product Description
Monel 400, a nickel-copper alloy with approximately 63% nickel and 28-34% copper, is renowned for its exceptional corrosion resistance in marine and chemical environments. As a versatile wire product, it combines good weldability, moderate strength, and toughness, making it suitable for a variety of industrial uses. This alloy excels in flowing seawater where low corrosion rates prevent erosion and cavitation damage. Commonly used in UNS N04400 specifications, Monel 400 wire is non-magnetic in many heats and offers reliable performance in reducing conditions, positioning it as an essential material for marine fixtures, propeller shafts, and chemical equipment across global offshore and coastal projects.
Exhibits minimal pitting and crevice corrosion, ideal for marine engineering and offshore installations.
Withstands hydrofluoric acid, sulfuric acid, hydrochloric acid, and alkaline solutions, ensuring longevity in chemical processing environments.
Offers tensile strength of 75-90 ksi (annealed) and yield strength of 25-50 ksi, maintaining performance from sub-zero to elevated temperatures up to 1000°F.
Facilitates easy forming and heat transfer, suitable for electrical components and heat exchangers in marine applications.
Prevents failures in freshwaters and non-oxidizing chloride solutions, enhancing safety in high-stress marine wire uses.
Compatible with standard welding techniques, allowing seamless integration into custom marine fixtures and UNS N04400 alloy assemblies.

FAQ
1.What is Monel 400 nickel-copper alloy wire made of?
Monel 400 (UNS N04400) is primarily composed of 63% nickel (plus cobalt), 28-34% copper, with minor elements like iron (up to 2.5%), manganese (up to 2%), and carbon (up to 0.3%). This composition provides its signature high corrosion resistance in marine and acidic environments.
2.How does Monel 400 wire perform in seawater corrosion resistance?
It offers excellent resistance to rapidly flowing seawater and brackish water, with low corrosion rates and minimal pitting or crevice attack. However, stagnant conditions may induce localized corrosion, so it's best for dynamic marine applications like propeller shafts and pumps.
3.What are the mechanical properties of high-strength Monel 400 UNS N04400 wire?
In annealed form, it has a tensile strength of 75-90 ksi, yield strength of 25-50 ksi, and elongation of 25-45%. Cold-drawn versions can reach higher strengths (up to 130 ksi), making it suitable for tough marine engineering demands.
4.Is Monel 400 alloy wire suitable for acid-resistant applications in chemical processing?
Yes, it excels in reducing acids like hydrofluoric, sulfuric, and hydrochloric, as well as alkalis, but it's not recommended for oxidizing environments. It's widely used in chemical plant equipment for its durability.
5.Can Monel 400 marine wire be welded or machined easily?
Absolutely, it has good weldability using standard techniques and moderate machinability, especially in its free-machining variant (Monel R-405). This makes it versatile for custom marine fixtures and offshore installations.
