Non-Magnetic N8 Pure Nickel Wire for Precise Temperature Control and Anti-Interference
N8 Pure Nickel Wire refers to a high-purity nickel alloy, often known for its excellent resistance to corrosion and oxidation in various demanding environments. N8 is a commercially pure nickel with a high percentage of nickel content, typically around 99.6% to 99.9%. It is similar in properties to other pure nickel alloys like Nickel 200 or Nickel 201 but can vary slightly based on specific industry standards and applications.
N8 Pure Nickel Wire is highly regarded for its purity, excellent corrosion resistance, and good electrical and thermal conductivity. It is used extensively in industries such as chemical processing, marine, aerospace, and electronics. Its non-magnetic properties, combined with high-temperature stability and formability, make it a versatile material for a wide range of demanding applications.

Some key features of Pure Nickel Wire N8 alloy include:
The alloy's high purity ensures exceptional resistance to corrosion and oxidation, making it ideal for aggressive environments.
N8 exhibits outstanding resistance to a wide range of acids, alkaline solutions, and seawater, making it highly effective for chemical processing, marine, and industrial applications.
N8 has good thermal and electrical conductivity, allowing it to be used in applications that require good heat and electrical transfer, such as electrical wire and components.
N8 is non-magnetic, making it useful in applications where magnetic properties must be avoided, such as in electronics and sensitive equipment.
It is easy to machine, form, and weld, which makes it highly adaptable for various manufacturing processes, including wire drawing, forging, and brazing.
While the alloy has moderate tensile strength (comparable to other pure nickel alloys), it provides good ductility and toughness, which makes it suitable for applications where flexibility and resistance to fracture are essential.
N8 retains its mechanical properties and corrosion resistance at elevated temperatures, typically up to 600°C (1112°F), allowing it to be used in high-temperature industrial environments.
Commonly used in electrical components, industrial processing, heat exchangers, aerospace, and marine applications where resistance to corrosion, oxidation, and high temperatures is essential.
N8 is particularly resistant to stress corrosion cracking in alkali solutions and other corrosive environments, making it ideal for high-stress applications.
