Monel R405 Composition
Description:
Nickel-copper alloy R-405 has a greater sulfur content making it a free-machining grade of alloy 400. With the same corrosion resistance and physical properties of 400 it possesses a different range of mechanical properties and us generally used for automatic screw-machining stock and is not recommended for other applications.
Nominal Composition in Percent:
Ni 66.50
Fe 2.50
Si 0.50
Mn 2.00
C 0.300
Cu 31.00
S 0.060
UNS Number:
N04405
Other Standard Specifications:
ASTM B164, QQ-N-281
Density:
8.80 g/cm3 (0.318 lbs/in2)
Exceptional Properties:
Very hard material, resistanct to corrosion, great strength

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
