Monel R-405 (UNS N04405) is a free-cutting grade of Alloy 400. Its higher sulfur content enhances machinability. While sharing similar corrosion resistance and physical properties with Alloy 400, it exhibits slightly different mechanical performance characteristics. This alloy is primarily used in automatic screw machines and is not recommended for other applications.
The density of the alloy is ρ=8.80g/cm³
