Nickel 200 Pure Nickel – Corrosion-Resistant Caustic Handling Material for Demanding Industries | Wisuno
In the demanding world of industrial materials, few alloys offer the combination of purity, versatility, and corrosion resistance found in commercially pure nickel. Among the most trusted grades is Nickel 200—a material that has earned its place across chemical processing, electronics, energy, and beyond. Wisuno Specialty Materials Technology (Nanjing) Co., Ltd. supplies high-quality Nickel 200 in multiple forms—including tube, plate, bar, strip, and wire—engineered to perform in the most corrosive environments.
Nickel 200 possesses the full physical and chemical properties of metallic nickel, offering outstanding resistance to strong alkalis, neutral and weak acidic media, while remaining stable in air, fresh water, and seawater. Its relatively higher carbon content—up to 0.10%—gives it a distinct advantage over lower-carbon grades like Ni201, particularly in hot concentrated alkaline solutions where its corrosion resistance truly excels. The material also performs exceptionally well in alkaline and neutral salt media such as carbonates, nitrates, sulfates, chlorides, and acetates.
With a density of 8.89 g/cm³ and a melting point ranging from 1435°C to 1446°C, Nickel 200 is built to withstand extreme conditions. Its mechanical properties are equally impressive—typical tensile strength spans 415–585 MPa, yield strength ranges from 105–310 MPa, and elongation reaches 35–55%, offering a reliable balance of strength and formability.
The applications of Nickel 200 span a remarkably diverse range of industries. In the chemical and caustic soda sector, it is used for filter meshes, chlor-alkali electrolysis electrodes, reactor linings, piping cladding, and evaporator internals. In electronics, it serves as battery tabs and current collectors, semiconductor lead frames, fuse elements, precision resistors, and magnetostrictive transducers. The electric light source industry relies on it for lamp lead-in wires, HID electrodes, and filament supports. Machinery manufacturing applications include metal wound gaskets, bellows, and springs for alkaline environments.
Emerging sectors are also turning to Nickel 200. In new energy and environmental protection, it is used as electrode material in molten carbonate fuel cells (MCFC) and solid oxide fuel cells (SOFC), as well as in alkaline water electrolysis systems for hydrogen production. The food and pharmaceutical industries utilize it in alkaline CIP environments and for linings in high-purity API and WFI storage. Even jewelry and musical instruments benefit from its low allergenicity and unique tonal properties. For laboratory and research applications, it serves as crucibles, boats, and even 3D printing feedstock.
From nuclear reactor components to automotive catalytic converter support meshes, Nickel 200 continues to prove its worth as a corrosion-resistant, high-purity material that industry professionals trust.
