200 Series Nickel (Nickel 200 and Nickel 201)
200 Series Nickel Uses and Considerations
200 Series Nickel (Nickel 200 and Nickel 201) are commercially pure forms of Nickel (99.6%) featuring excellent mechanical properties and corrosion resistance to alkalis, high thermal conductivity, and good electrical conductivity. Thanks to its lower carbon content at 0.02%, Nickel 201 offers superior formability compared to Nickel 200 at 0.15%. Top industry uses include:
Food & Chemical Processing Equipment: Nickel 200 and Nickel 201’s positive electrical and thermal properties make them excellent metals for use in food processing equipment, where materials are often exposed to harsh chemicals and varying pH levels. In chemical processing, good electrical conductivity helps maintain precise control over reaction conditions, improving process efficiency and safety.
High thermal conductivity is also crucial for efficient heat transfer in the equipment to help maintain temperature control, which is essential for processes like pasteurization and sterilization. The 200 Series Nickel also possesses excellent mechanical properties, including good ductility and toughness, which enable the metal to withstand mechanical stress and wear over time. This durability is vital for the longevity and reliability of food and chemical processing equipment.
Electronic Components: The purity of Nickel 200 and 201 ensures minimal resistance to electrical current, and the excellent electrical conductivity properties make them ideal for use in electrical components where efficient electron flow is crucial. This also benefits applications involving electrical heating elements and temperature control systems. Nickel’s stability at high temperatures makes it suitable for use in components that operate under varying thermal conditions, such as resistors, thermocouples, fuel cells, anodes, battery connections, and heating elements.
Marine & Water Treatment: With strong corrosion resistance to alkalis, Nickel 200 and 201 are common in marine and seawater applications where corrosion due to saltwater is a significant concern. Their biocompatibility also ensures they do not negatively impact marine life. Because Nickel does not leach harmful substances into water, it is safe for water treatment applications where maintaining water purity is essential.
The excellent mechanical properties of Nickel 200 and Nickel 201, including their high tensile strength and ductility, make them ideal for components that must withstand the physical stresses encountered in marine and water treatment environments. Finally, the high thermal conductivity of these Nickel alloys aids in heat dissipation in water treatment systems, improving efficiency and performance.
What you need to know about buying Nickel 200 and 201:
- Nickel 200/201 is highly resistant to caustic soda and other alkalis, brines, seawater, acids, and chlorides.
- Can be easily formed and welded.
- 200 Series Nickel is ferromagnetic.
- Nickel 201 is typically selected for higher temperature applications up to 1250°F.
- Should be machined in the annealed condition when possible as the material can harden
