Common Trade Names: Monel R405; Alloy R405; Nickel 405; Monel 405; Alloy 405.

Monel nickel-copper alloy R-405 (UNS N04405) is the free-machining grade of alloy 400. Its greater sulfur content enhances machinability. It 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

Available Product Forms: 

Round bar, sheet, plate, pipe,hexagon and wire ect
