Common Monel Alloy Grades

Monel alloys are nickel-copper alloys known for their excellent resistance to corrosion, especially in marine and chemical environments. These alloys maintain good mechanical strength while offering strong resistance to seawater, acids, and alkaline solutions.

Different Monel grades are designed for different mechanical and environmental requirements. The following alloys are among the most commonly used.

One-piece deformable Monel alloy (machinable and formable)

Suitable for processes such as rolling and forging, this is the most common form used in industry.

‌Monel 400‌ (UNS N04400)
The most basic and widely applied grade, Monel 400 has a single-phase solid solution structure with high strength and excellent overall corrosion resistance. It performs well in hydrofluoric acid, hydrochloric acid, sulfuric acid, alkaline solutions, and seawater, and is commonly used to manufacture pump shafts, valves, fasteners, and heat exchangers. Its nickel content is approximately 63–70%, with copper at 28–34%.

‌Monel K500‌ (UNS N05500)
Based on Monel 400, this alloy adds aluminum and titanium, allowing for age hardening to significantly increase strength and hardness. Its tensile strength can reach up to 1310 MPa, making it suitable for corrosion-resistant components under high-stress conditions, such as centrifugal pump shafts, turbine blades, and springs. Although its corrosion resistance is slightly lower than that of Monel 400, it still maintains excellent performance in most media.

‌Monel R-405‌ (UNS N04405)
Sulfur is added to improve machinability, making it ideal for manufacturing bolts, nuts, and other components requiring mechanical processing. It is often used together with Monel 400 in valve systems.

‌Monel 404‌ (UNS N04404)
With high copper content, this alloy has low thermal conductivity and low permeability, and is primarily used in electronic packaging, waveguides, and brazing materials.

‌Monel 406‌ (UNS N04406)
A low-carbon, high-nickel alloy suitable for specific electronic and electrical applications, featuring a low temperature coefficient of electrical resistance.

Two-piece cast Monel alloys

Used in the casting production of complex-shaped parts, commonly found in valve bodies and large-scale components.

‌M35-1‌ (GB/T 35740—2017)
A casting grade specified by Chinese standards, with moderate carbon and silicon content, offering good casting and mechanical properties. It is widely used in industrial valve manufacturing.

‌Monel 410, 505, 506‌
Casting alloys under American standards, among which Monel 505 and 506 are high-silicon, high-strength types suitable for wear-resistant components.

Other special grades

Alloys such as ‌Monel C, 403, 411, 501, 502‌ are deformation or age-hardenable alloys developed for specific applications in electronics, high-temperature environments, or precision components, though their usage is relatively limited.
