Types of Nickel Alloy Grades and Families
Nickel alloys are available in various specialized grades, which are categorized into the following families based on their composition and properties:
- Monel®. Monel is the trademarked name for a family of nickel-copper alloys. They exhibit good temperature resistance, high strength, and exceptional corrosion resistance in chemical and marine environments.
- Inconel®. This family of nickel-chromium-based superalloys has high mechanical performance, superior oxidation and corrosion resistance, and exceptional high-temperature strength and integrity in extreme environments.
- Incoloy®. These are a family of nickel-iron-chromium alloys with several grades that offer resistance to specific chlorides and acids, oxidation resistance, and high-temperature strength. The Incoloy 9xx series alloys are precipitation-strengthened, and the 8xx series are solid-solution strengthened.
- Hastelloy®. This family of nickel-based high-performance superalloys includes B-type alloys (B-2, B-3) compatible with strong reducing acids, C-type alloys (C-22, C-276) suitable for reducing and oxidizing environments, and G-type alloys (X) designed for highly oxidizing and phosphoric acids.
- Invar®. This is a nickel-iron alloy with an extremely low coefficient of thermal expansion, which makes it impervious to temperature changes. Invar is composed of 64% iron and 36% nickel and exhibits excellent dimensional stability around fluctuating temperatures.
- Commercially Pure Nickel. This versatile alloy is highly thermally and electrically conductive, performs well in alkaline environments, and has exceptional resistance to chemicals. Nickel 200 offers excellent toughness and ductility, while Nickel 201 has a lower carbon content that prevents embrittlement at extreme temperatures.
