First developed by researchers at Wiggin Alloys in England in the 1940’s, Inconel is a family of nickel-chromium alloys. Because of their high performance properties, these alloys are often used in extreme environments. Sometimes called “Inco”, inconel also has a variety of trade names, including Inconel 625, Chronin 625, Altemp 625, Haynes 625, Nickelvac 625 and Nicrofer 6020.
The composition of different Inconels can vary greatly, but they all are predominantly composed of nickel and chromium. For example, alloy 625 is 58% Nickel and 20-23% chromium.
Inconels are resistant to both oxidation and corrosion. When exposed to heat, Inconel forms a thick, stable shielding layer that protects the surface from corrosion. Furthermore, Inconel retains its strength over a wide range temperatures, whereas other materials, like aluminum or steel, would succumb to creep.
Because of its resistance to heat and corrosion, Inconel is often used in extreme environments. Some of these applications include:
Inconels have several drawbacks. Welding them can be difficult because of potential cracking; however, a few alloys have been developed to overcome this problem. Additionally, machining and shaping nickel alloys can be difficult due to rapid work hardening.
