NICKEL AND NICKEL ALLOY

Nickel is the chief constituent of a number of non-ferrous alloys which are used in special applications in aircraft work.
The main feature common to all of these alloys is their good corrosion resistance.

Monel

-It can be only cold worked

-Monel is a high nickel copper alloy with excellent corrosion resistance and high strength

-Monel used in aircraft industry are in the form of rivet, bolts, nuts, lockwire and the

manufacture of Dzus fastener grommets

-Its toughness and excellent resistance to attack of corrosive medium are valuable qualities

Inconel

-Combining excellent resistance to high temperature oxidation with a high resistance to many

types of corrosion

-Inconel welds readily and gives a strong ductile weld which resists corrosion

-The heat treatment consists only of an annealing which will relieve internal stresses due to

cold working and soften the metal

Nimonic

-Possess good fatigue properties

‘K’ Monel

-This alloy is often used in the vicinity of instrument panel

Inconel ‘X’

-It is used for gas turbine rotor blades and wheels, after burners and ram jets
