Alloy Geek Monel 405 Standard
Alloy 405, a nickel-copper alloy, is celebrated for its versatility and excellent resistance to corrosion in various challenging environments. With a well-defined chemical composition and a range of advantageous properties, Alloy 405 is a reliable choice for applications requiring both durability and performance.
Chemical Composition Range:
- Nickel (Ni): 63.0% min
- Copper (Cu): 28.0% - 34.0%
- Iron (Fe): 2.5% max
- Manganese (Mn): 2.0% max
- Carbon (C): 0.3% max
- Silicon (Si): 0.5% max
- Sulfur (S): 0.025-0.060%
Corrosion Resistance: Alloy 405 exhibits remarkable resistance to various corrosive environments, including seawater, chemical processing, and marine applications, ensuring prolonged durability and reliability.
High Temperature Strength: The alloy retains its mechanical integrity and structural strength at elevated temperatures, making it suitable for applications involving heat and stress.
Ductility and Versatility: Alloy 405 offers excellent ductility, allowing for ease of forming, welding, and fabrication, making it highly versatile in manufacturing processes.
High Sulfur: Monel 405 is the free-machining version of Monel 400. Its greater sulfur content enhances machinability.
- Applications: Monel 405 has essentially the same corrosion resistance and physical properties as alloy 400, but a slightly different range of mechanical properties. Alloy R-405 is used chiefly for automatic screw-machine stock and is not generally recommended for other applications.
Other Names for Alloy 405:
- UNS N04405: UNS (Unified Numbering System) designation for Alloy 405, commonly used for standardization and identification.
- Monel R-405: An alternate designation, emphasizing the alloy's composition and properties.

Reference Material (RM): A reference material, or RM, is a material with a known composition or property that is used for informational purposes to look at analytical instruments, methods, or procedures. It serves as a point of comparison to ensure the accuracy and reliability of measurements. Reference materials can vary in terms of their level of characterization and traceability. Some reference materials may have well-defined properties, but they might not have undergone the rigorous testing and certification process that certified reference materials (CRMs) undergo. Reference Material chemical compositions are for information purposes.
Certified Reference Material (CRM): A certified reference material, or CRM, is a type of reference material that has been thoroughly analyzed and characterized using multiple validated methods to determine its composition or properties. The results of these analyses are then used to establish certified values, along with associated uncertainties. CRMs are produced and certified by accredited organizations or laboratories following internationally recognized standards, such as ISO Guide 34 and ISO/IEC 17025. The certification process includes interlaboratory comparison and statistical analysis to ensure accuracy and traceability.
In summary, the main difference between a reference material and a certified reference material lies in the level of characterization, validation, and certification. CRMs have undergone a more comprehensive and rigorous testing process, resulting in certified values and uncertainties that can be confidently used for instrument calibration, quality control, and research. Reference materials, on the other hand, can provide a point of comparison but might not have the same level of certification and traceability as CRMs. When accuracy and traceability are critical, certified reference materials are preferred.
