Nickel201/N 02201/2.4061/N7 Pure Nickel Metal Good Weldability for Various Uses

Nickel 201 (also known by its ASTM designation N02201) is a commercially pure form of nickel with a minimum nickel content of 99.6%. It is highly resistant to corrosion, particularly in alkaline and neutral environments, making it ideal for applications in chemical processing, aerospace, and electronics. Products such as nickel 201 wire, round nickel wire, ultra thin nickel wire, and micro nickel wire are commonly used in these industries. Nickel wire np1, nickel wire np2, and nickel wire 99.999 (high-purity grades) are particularly suited for high-precision and corrosion-sensitive applications.

Nickel 201 has good mechanical properties and is suitable for a wide range of temperatures. It is often utilized in environments exposed to caustic soda, seawater, and other corrosive agents. Specialty forms such as 0.025mm nickel wire, russian nickel wire 0.025 mm, pure nickel wire mesh, and ni200 nickel wire mesh cater to industries requiring ultra-fine or mesh configurations. Additionally, nickel 6n wire—noted for its ultra-high purity—and products offered with transparent nickel wire prices or nickel wire price per meter ensure versatility for both bulk and precision requirements in electronic, electrical, and chemical components.

Key Features of Nickel201/N 02201/2.4061/N7 Alloy:

Nickel 201 (also known as N02201, 2.4061, and N7) is a commercially pure nickel alloy, known for its excellent combination of mechanical properties and resistance to corrosion. Here are the key features of this alloy:

1. High Purity and Composition:

• Nickel Content: Minimum of 99.6%, which gives the material its pure, high-quality characteristics.
• It is often referred to as "pure nickel" since it has very low levels of other elements like iron, copper, and carbon, which contribute to its specific properties.

2. Corrosion Resistance:

• Excellent Resistance to Corrosive Environments: Nickel 201 is highly resistant to corrosion in a variety of environments, including:

Alkaline solutions: It has excellent resistance to caustic alkalis, such as sodium hydroxide.

Acidic solutions: While it does not have the same resistance to acids as some other alloys (e.g., nickel-based alloys like Inconel), it still performs well in non-oxidizing acids and is resistant to corrosion in mild conditions.

Seawater: It is resistant to seawater corrosion, which makes it useful in marine applications.

3. Mechanical Properties:

• Ductility and Strength: Nickel 201 has good ductility, meaning it can be drawn, formed, or bent without breaking. It also retains strength at elevated temperatures.
• Temperature Resistance: It maintains good mechanical properties at temperatures up to 600°C (1112°F), making it suitable for high-temperature applications.
• Low Magnetic Permeability: The alloy is not magnetic, which is important for applications where magnetic interference needs to be minimized, such as in electronics and instrumentation.

4. Electrical and Thermal Conductivity:

• Nickel 201 offers good electrical and thermal conductivity, making it suitable for use in electrical components, including connectors, and in heat exchangers.

5. Fabricability:

• Excellent Formability: It can be easily formed, welded, and machined. This makes it ideal for applications that require precision and intricate shapes, including aerospace, electronics, and chemical processing.
• Weldability: The material has good welding properties and can be used in a variety of welding processes, such as TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas).

6. Non-Magnetic Properties:

• Nickel 201 is non-magnetic, which is important for specialized electronic components and magnetic shielding.

Applications:

• Chemical and Petrochemical Industries: Due to its resistance to corrosive environments, it's used for pipes, tanks, and other components exposed to corrosive chemicals.
• Aerospace and Electronics: Components like electrical connectors, sensors, and other electronic parts where corrosion resistance, conductivity, and non-magnetic properties are essential.
• Marine Applications: It is used in parts exposed to seawater or other marine environments, such as heat exchangers, marine engineering parts, and boat components.
• Vacuum Systems and High-Temperature Applications: Because of its good strength and stability at high temperatures, it's used in vacuum furnace components and other high-temperature settings.

Availability and Cost:

• Widely Available: Nickel 201 is readily available in a variety of forms, including sheets, plates, rods, wires, and tubes.
• Cost: Pure nickel alloys tend to be more expensive than other alloys (like stainless steel), but their performance in corrosive and high-temperature environments often justifies the cost in demanding applications.

Limitations:

• Lower Strength at Elevated Temperatures: While it performs well at higher temperatures, Nickel 201 is not as strong as some of the nickel alloys designed for extreme high-temperature environments (e.g., Inconel alloys).
• Moderate Resistance to Oxidizing Acids: It does not perform as well in highly oxidizing acids like nitric acid compared to other nickel alloys or stainless steels.

Alloy Designation & Standards:

• ASTM B160: Nickel 201 is often referenced by the ASTM B160 standard, which defines its specifications for wire and bar stock.
• UNS N02201: The Unified Numbering System (UNS) designation for this material.
• 2.4061: The European designation for the material, commonly used in industries following European standards.
• N7: A shorthand reference for pure nickel alloys like Nickel 201, used in specific applications or industries.

In summary, Nickel 201 is a versatile, corrosion-resistant alloy that is used in demanding environments, especially in chemical processing, aerospace, electronics, and marine industries. It is ideal when high-purity nickel with excellent corrosion resistance, formability, and non-magnetic properties is required.
