Product Description
A precipitation-hardenable nickel-copper alloy
that combines the corrosion resistance of
MONEL alloy 400 with greater strength and
hardness. It also has low permeability and is
nonmagnetic to temperatures as low as -150°F
(-101°C). Used for pump shafts, oil-well tools and
instruments, doctor blades and scrapers, springs,
valve trim, fasteners and marine propeller shafts.
