Nickel 800 alloys are known by several names depending on the standard, specification, or drawing being used. Understanding these alternate names matters because the same alloy can appear under different designation systems across quotes, certifications, standards, and legacy prints. For buyers and engineers working with wire, this is especially important, since Nickel 800 may be referenced through material standards tied to specific product forms and applications rather than by one simple trade name alone.
Alloy 800 is a general commercial shorthand and conversational naming style used throughout the nickel alloy industry when the nickel-iron-chromium alloy family is already understood. Best for casual product discussions, internal communication, sales conversations, and simplified technical language where the audience already knows the material is a nickel alloy. It is concise, recognizable, and easy to read, but it is less precise than formal designation systems because the term “alloy” by itself does not identify the governing specification, standards organization, or numbering system associated with the material. Alloy 800 is widely recognized throughout industry as the nickel-iron-chromium alloy commonly known as Nickel 800 or Incoloy® 800, valued for its excellent resistance to oxidation, carburization, and high-temperature corrosion, as well as its long-term thermal stability in petrochemical, power generation, heat-treating, and industrial processing applications.
