Nickel 200 is a commercially pure wrought nickel wire alloy containing approximately 99.0% minimum nickel, providing excellent corrosion resistance, outstanding electrical and thermal conductivity, and good mechanical properties across a wide range of temperatures. The high nickel content of Nickel 200 provides exceptional resistance to caustic alkalis, neutral and reducing chemical environments, and a variety of corrosive media. Nickel 200 is commonly used for wire forms, electrical and electronic components, aerospace and defense applications, chemical processing equipment, battery systems, fasteners, and other demanding applications requiring high purity, corrosion resistance, conductivity, and reliable long-term performance.
Nickel 200 alloy wire is identified under multiple naming conventions, including grade, alloy, and UNS designations; depending on the specification, industry, or standard being used.

Nickel 200 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 200 may be referenced through material standards tied to specific product forms and applications rather than by one simple trade name alone.
Alloy 200 is a general commercial shorthand and conversational naming style used throughout the nickel alloy industry when the nickel 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 nickel. 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.
UNS N02200 is the official Unified Numbering System (UNS) designation for Nickel 200. Best for formal material identification, cross-referencing between industry standards, quality assurance documentation, mill certifications, engineering specifications, and multi-standard procurement requirements. This designation serves as the clearest and most unambiguous identifier when matching Nickel 200 across different specification systems and international standards. It is especially useful when a drawing, certification, purchase order, or compliance document requires a formal material designation rather than a commercial or trade-style name.
Commercially Pure Nickel, often abbreviated as CP Nickel, is a common industry designation for Nickel 200 because of its minimum nickel content of approximately 99.0%. Best for educational content, material specifications, chemical processing applications, and technical discussions focused on high-purity nickel alloys. This designation highlights the alloy’s exceptional purity, excellent corrosion resistance, and outstanding electrical and thermal conductivity while distinguishing Nickel 200 from nickel-based alloys that contain larger amounts of additional alloying elements. Though widely recognized throughout industry, CP Nickel is a descriptive classification rather than a formal standards designation such as UNS N02200.
Pure Nickel 200 is a common commercial and technical designation for Nickel 200, emphasizing its high-purity nickel content of approximately 99.0% nickel minimum. Best for product descriptions, educational content, material specifications, and discussions focused on corrosion resistance and conductivity. This designation highlights the alloy’s exceptional purity, excellent resistance to many corrosive environments, and outstanding electrical and thermal conductivity, making it a popular choice for chemical processing, electronics, aerospace, battery, and industrial applications. While widely recognized throughout industry, Pure Nickel 200 is a descriptive name rather than a formal material designation such as UNS N02200.
Low Carbon Nickel 200 is a descriptive term sometimes used to refer to Nickel 200 when emphasizing its controlled carbon content and excellent corrosion resistance. Best for technical discussions, material comparisons, and applications where purity and metallurgical performance are important. This designation highlights the alloy’s high nickel content and relatively low carbon levels, which contribute to its excellent resistance to corrosive environments, good mechanical properties, and outstanding electrical and thermal conductivity. While commonly used as a descriptive name, Low Carbon Nickel 200 is less precise than formal material designations such as UNS N02200 and should not be confused with Nickel 201, which is the dedicated low-carbon grade of commercially pure nickel.
ASTM B160 Nickel 200 is the designation used when Nickel 200 is supplied in accordance with ASTM B160, the industry specification covering nickel rod and bar products. Best for engineering specifications, procurement documents, quality requirements, and applications involving Nickel 200 rod, bar, and machined components. This designation helps identify the alloy within ASTM-controlled requirements and is frequently referenced in technical documentation, certifications, and purchasing specifications where the mechanical and chemical properties of Nickel 200 (UNS N02200) must conform to ASTM standards.
W.Nr. 2.4066 is the Werkstoffnummer (material number) designation for Nickel 200 and is widely used in European engineering specifications, certifications, and technical documentation. Best for international procurement, material cross-referencing, and quality documentation. The designation W.Nr. 2.4066 provides a standardized material identifier that helps engineers and buyers match Nickel 200 across European and global standards systems while identifying it as a commercially pure nickel alloy known for its excellent corrosion resistance, conductivity, and high-purity composition.
DIN 2.4066 is the German material designation for Nickel 200 and is commonly used in European engineering specifications, material certifications, and procurement documents. Best for international sourcing, technical documentation, and material cross-referencing. The designation DIN 2.4066 provides a standardized identifier that helps engineers and buyers match Nickel 200 across global standards systems while identifying it as a commercially pure nickel alloy known for its excellent corrosion resistance, electrical conductivity, thermal conductivity, and high-purity composition.
EN 2.4066 is the European material number designation for Nickel 200 within the EN (European Norm) standards system. Best for European engineering specifications, international procurement, material certifications, technical documentation, and cross-referencing between global nickel alloy standards. The use of EN 2.4066 immediately identifies the material according to a standardized European classification, making it easier to match Nickel 200 across international supply chains and regulatory requirements. This designation is widely recognized throughout Europe and is commonly found on mill certificates, engineering drawings, quality documentation, and material specifications where compliance with European standards is required.
