Nickel 200 (UNS N02200)
Nickel 200 is a commercially pure wrought nickel (99.6% minimum) known for its exceptional mechanical properties and unyielding resistance to a vast range of corrosive environments. As a solid-solution strengthened material, it provides a unique combination of high thermal and electrical conductivity, low gas content, and low vapor pressure. It is specifically preferred in applications where maintaining the total purity of the end product—such as in food or synthetic fiber production—is a critical requirement.
At Aries Alloys, we supply Nickel 200 that meets the stringent requirements of the chemical and electronic industries. Our inventory is selected for its reliability in handling caustic alkalis and its ability to maintain structural stability across a wide temperature spectrum.
Key Performance Attributes
- Unmatched Caustic Resistance: Widely considered the "standard" for handling caustic soda (sodium hydroxide) at all concentrations, even in the molten state.
- High Conductivity: Offers superior thermal and electrical conductivity compared to most nickel-based alloys and stainless steels.
- Magnetic & Magnetostrictive Properties: Retains distinct magnetic characteristics that are essential for specialized electronic and transducer components.
- Excellent Ductility: Highly fabricable and malleable, allowing for easy forming, spinning, and welding into complex industrial shapes.
- Resistance to Distilled Water: Outstanding longevity in distilled and natural waters, resisting corrosion even at high flow velocities.
Technical Profile & Composition
The Purity Standard:
The strength of Nickel 200 lies in its high nickel concentration (99.0% min). While it contains trace amounts of Iron, Manganese, and Silicon to improve workability, it remains essentially unalloyed, ensuring it retains the core properties of elemental nickel.
Mechanical & Physical Indicators:
- Density: 8.89 g/cm3
- Melting Range: 1435° C - 1446° C (2615° F - 2635° F)
- Electrical Resistivity: 9.6 \times 10^{-8} \Omega m
- Magnetic Curie Temperature: 360° C (680° F)
- Maintains good impact strength and toughness even at cryogenic temperatures.
