Monel R405 Composition

Print Email

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

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
