Specifications: Standards and Classifications
Iron Nickel Alloy Plate is governed by standards like ASTM F15, ASTM F30, and AMS 5221, ensuring quality across grades such as Invar 36, Kovar, and Alloy 42. These standards define properties like thermal expansion, corrosion resistance, and finish. For instance, an Invar 36 Iron Nickel Alloy Plate aligns with ASTM F15 for low thermal expansion applications, while Kovar offers superior sealing properties per the same spec. Classification splits into types such as Invar 36 (low expansion), Kovar (glass-to-metal sealing), and Alloy 42 (magnetic applications), with grades further distinguished by finishes like bright polished or mill finish. Iron Nickel Alloy Plate, typically thicker than 0.1875″ (4.76mm), adheres to similar standards but is often tailored for precision engineering applications.
Size Range: Dimensions and Customization
Iron Nickel Alloy Plate comes in a wide range of sizes to suit diverse needs. Common dimensions include:
- Length and Width: Standard sizes like Iron Nickel Alloy Plates 48″ x 96″ dominate, though options range from 36″ x 96″ to 60″ x 120″.
- Thickness: Thin Iron Nickel Alloy Plate starts at 0.1875″ (4.76mm) and goes up to 1″ (25.4mm), while thicker custom variants can exceed 1″ for specialized applications.
- Custom Options: Suppliers like Online Metals and Metals Depot offer cut-to-size services, allowing buyers to specify exact dimensions for Iron Nickel Alloy Plate thickness or plate needs.
This flexibility ensures Iron Nickel Alloy Plate fits everything from precision engineering to large industrial builds.
Types: Forms, Processes, and Finishes
Iron Nickel Alloy Plate comes in various forms and finishes, each tied to specific manufacturing processes:
- Forms: Flat Iron Nickel Alloy Plate, Iron Nickel Alloy perforated plate (with round or custom holes), and Iron Nickel Alloy patterned plate for enhanced stability.
- Processes: Cold rolled Iron Nickel Alloy Plate offers a smooth, precise finish (e.g., bright rolled finish), while hot rolled Iron Nickel Alloy Plate suits thicker, less polished applications like structural components.
- Surface Treatments: Options include bright rolled (smooth, matte), No. 4 (brushed), BA (bright annealed), and polished finishes. Iron Nickel Alloy perforated plate adds functionality with hole patterns for precision engineering or thermal management applications.

Frequently Asked Questions
Q: What is a nickel-iron alloy?
A: A nickel-iron alloy plate, such as Invar or Monel, combines nickel and iron to offer unique properties like low thermal expansion, corrosion resistance, and high strength, ideal for precision and industrial applications.
Q: Does iron nickel alloy rust?
A: Iron nickel alloy plates resist rust well due to nickel’s protective oxide layer. However, in highly oxidizing environments, alloys with higher iron content may show minor corrosion without proper care.
Q: Is nickel alloy stronger than stainless steel?
A: Nickel-iron alloy plates, like Inconel, often surpass stainless steel in strength, especially at high temperatures, and offer better corrosion resistance, though stainless steel may be more cost-effective for general use.
Q: What is nickel iron plate alloy used for?
A: Nickel-iron alloy plates are used in aerospace for structural components, chemical processing for reactors, and electronics for magnetic shielding, thanks to their durability and unique thermal properties.
Q: Why is alloy iron and nickel plate advantageous?
A: Iron nickel alloy plates provide low thermal expansion (e.g., Invar), excellent corrosion resistance, and high strength, making them ideal for precision instruments, marine environments, and high-stress applications.
Q: Is iron nickel alloy strong?
A: Yes, iron nickel alloy plates are very strong, with tensile strengths often exceeding 1000 MPa (e.g., Inconel), and they maintain their strength at elevated temperatures, perfect for demanding industrial uses.
