Nickel Alloys

Nickel and nickel alloys are non-ferrous metals with high strength and toughness, excellent corrosion resistance, and superior elevated temperature properties. Products differ in terms of composition, grade, shape, dimensions, and features. Commercially pure, unalloyed, or very low alloy nickel does not contain or contains only very small amounts of alloying elements. By contrast, nickel alloys contain significant amounts of added elements or constituents. Clad or bimetal stock consists of two different alloys that are bonded integrally together. Metal matrix composites have a composite or reinforced metal or alloy matrix filled with a second component, which may be in particulate, chopped fiber, continuous filament, or fabric form. Other unlisted, specialty or proprietary nickel and nickel alloys are also available. These materials are often based on a unique alloy system, use a novel processing technology, or have properties tailored for specific applications.

Many nickel and nickel alloys meet the compositional standards of the Unified Numbering System (UNS), a specification established by the American Society for Testing and Materials (ASTM), the Society of Automotive Engineers (SAE), and metal trade associations such as the American Iron and Steel Institute (AISI). The UNS assigns metals and alloys a lettered prefix and a five-digit number. Nickel and nickel alloys belong to the UNS N category and have designations such as UNS N02200. Other standards for nickel and nickel alloys include casting grades, European Norm (EN), American Society of Mechanical Engineers (ASME) standards, and U.S. military specifications (MIL-SPEC). QQ and QQS prefixes are used to designate specific MIL-SPEC metals.

Selecting nickel and aluminum alloys requires an analysis of dimensions, production processes, and performance features. Outer diameter (OD), inner diameter (ID), overall length, and overall thickness are important dimensions. Most materials are cast, wrought, extruded, forged, cold-finished, hot-rolled, or formed by compacting powdered metals or alloys. Performance features for nickel and nickel alloys include resistance to corrosion, heat, and wear.

Inconel Nickel Alloys

Inconel, a robust nickel alloy, is available in wire mesh, perforated metal, expanded metal, and bar grating. Inconel wire mesh is renowned for its superior strength, resistance to extreme temperatures, and corrosion and oxidation resistance, making it ideal for high-stress applications like petrochemical, oil & gas, and chemical processing. Perforated Inconel metal offers high structural integrity, ensuring longevity in corrosive environments. Inconel expanded metal demonstrates increased tensile strength, making it perfect for architectural applications. Lastly, Inconel bar grating provides a durable, non-slip surface that remains stable even under intense conditions and is widely utilized in industrial platforms. Each form harnesses Inconel’s unique properties, delivering performance-enhanced solutions for diverse industry needs.

Inconel Grades

  • Inconel 600 is renowned for its high temperature and corrosion resistance
  • Inconel 601 offers enhanced resistance to high-temperature oxidation
  • Inconel 625 excels in terms of its fatigue and stress-corrosion cracking resistance

Monel 400 Nickel Alloys

Monel 400 is a nickel-copper alloy known for its superior strength and excellent corrosion resistance, particularly in marine and chemical environments. With a composition of approximately 67% nickel and 23% copper, this alloy exhibits notable resistance to a wide range of corrosive conditions, including saltwater, acidic and alkaline substances. It also possesses high thermal conductivity and maintains its strength even at very low temperatures, making it a versatile material for numerous industries such as marine engineering, chemical processing, and oil & gas.

Monel 400, a highly durable nickel-copper alloy, is available in wire mesh, perforated metal, and expanded metal forms. Monel 400 wire mesh is prized for its corrosion resistance and strength, making it a preferred choice for marine and chemical processing applications. Perforated Monel sheet exhibits excellent mechanical properties at subzero temperatures, and its high structural integrity makes it ideal for use in architectural and oil & gas industries. Monel 400 expanded metal provides superior strength and hardness, which is particularly useful in the construction of high-load-bearing structures.
