Which Is More Expensive, Monel 400 Alloy or Ni-201?
Monel 400 alloy (UNS N04400 or MCu-28-1.5-1.8 or Ni68Cu28Fe) is a nickel-based alloy material with good corrosion resistance in seawater, chemical solvents, ammonia-sulfur-chlorine, hydrogen chloride, various acidic media such as sulfuric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid, organic acids, alkaline media, salts and molten salts.
Ni-201 is commercially pure nickel with very low carbon content and has been approved for service up to 1230°C in high-temperature environments. It is one of the most widely used materials in industry. It has very good mechanical properties and excellent corrosion resistance in many corrosion-resistant environments and is particularly resistant to caustic soda corrosion. Relative to Ni200, Ni201 contains less carbon and it is more suitable for working at 315C.
Monel 400 is slightly more expensive.

What Kind of Material Is Ni201? What Is the Difference Between N4 and N6?
- Ni201 nickel strip to the U.S. grade: N4, N6 corresponds to the ASME II in the Ni201 and Ni200. That is low carbon pure nickel and ordinary pure nickel (i.e. N4, Ni201, N6, Ni200).
- Nickel belt executive standard: N4/N6 pure nickel belt production executive standard GB/T2072-2007
- Nickel strip state (Vickers hardness): hard state (Y), semi-hard (Y2),1,4 hard (Y4), soft state (M).
- Nickel strip specification: wide band: 2~330mm, Thickness: 0.05~1mm, Length: =3000mm
- Packing, marking, transportation, and storage of nickel strips are according to GB88888.
- Nickel strip purity: 99.95% or more
- Nickel strip characteristics: good luster, ductility, solderability
- N4, N6 pure nickel strip difference: N4, N6 difference is in the C content that is: N4, N6 corresponds to ASME II in the Ni 201 and Ni 200 low carbon pure nickel and ordinary pure nickel (i.e., N4 / Ni201, N6).
Pure Nickel Strip
Containing more than 99.95% nickel, pure nickel has excellent mechanical properties. Pure nickel is particularly resistant to alkali corrosion, whether in high temperature or molten alkali, and is more stable, so it is mainly used in the alkali industry. At room temperature, nickel is extremely stable in seawater and salt solutions and organic media (such as fatty acids, phenols, alcohols, etc.). It is not resistant to corrosion by inorganic acids and is not stable in acetic acid and anthranilic acid.
Pure nickel has excellent mechanical properties and high corrosion resistance in many different environments and also has magnetostrictive and magnetic properties, high heat transfer, high electrical conductivity, low gas volume, and low vapor pressure. Good spot welding performance, high tensile tension, easy to operate.
Low resistivity (laptop battery pack combination preferred) can pass more than 50A current, is the power battery pack combination preferred This product is mainly used in the manufacture of nickel-metal hydride batteries, lithium batteries, combined batteries, and power tools, communication information, special lamps, and other industries.
Difference Between N4 and N6
- Chemical composition, N4 C content of less than 0.02% N6 C content of less than 0.15%, the rest of the element content is the same;
- Mechanical properties, in the M state, N4 Rm ≥ 350MPa, N6 Rm ≥ 380MPa
Note: N4 and N6 as shown above, mainly have a C content of the different, N4 is called low carbon pure nickel, and the rest of the element content is the same, due to the low carbon nature of N4, suitable for use in some specific circumstances, so good to communicate with the customer to use the environment or use, to avoid unnecessary trouble.
What Is the Material of Ni200 Nickel Foil?
Nickel alloy, two commonly used grades are N02200/NI200/N6 and N02201/NI201/N4
Ni200 alloy has the following properties:
Ni200 is pure commercial nickel with excellent mechanical properties and corrosion resistance, high thermal and electrical conductivity, low gas content, and low vapor pressure.
Ni200 Application Areas
Mining and marine extraction.
Equipment required to manufacture industrial sodium hydroxide at high temperatures above 300°C.
Ni200 Key Specifications
NI200 seamless pipe, NI200 steel plate, NI200 round steel, NI200 forgings, NI200 flanges, NI200 rings, NI200 welded pipe, NI200 steel strips, NI200 straight bars, NI200 wires and supporting welding consumables, NI200 round cake, NI200 flat steel, NI200 hexagonal bars, NI200 large and small heads, NI200 elbows, NI200 tee, NI200 machined parts, NI200 bolts and nuts, NI200 fasteners
The C content of Ni 201 and Ni 200 are not the same, and NI201 has better deep stamping and molding performance.
Generally speaking, the difference in corrosion resistance between the two is not significant, but in terms of deep drawing performance, NI201 is superior. Ultra-thin nickel foils, which are generally used for electronic components and electronic products, are deep processed using NI201 and higher NI205.
Excellent mechanical properties and high corrosion resistance in a variety of different environments, but also has magnetic, high heat transfer, high electrical conductivity, low gas volume low vapor pressure, and other characteristics, pure nickel 201 is mainly used for electronic products, high-precision chemical instrumentation and other products above.
