Monel R405 is a nickel copper alloy that is a free-machining grade of Monel 400 due to its higher sulfur content. Monel 405 has the same corrosion resistance and physical properties as Monel 400 although it has a different range of mechanical properties. R405 is used mostly in automatic screw machines.
