Formula: Ni
Form: Disk
Material: Nickel
CAS Number: 7440-02-0
Commodity: Metals
Nickel Disk is a precision-cut form of high-purity nickel offering excellent corrosion resistance, high electrical conductivity, and mechanical robustness. Its uniform surface and dimensional stability make it suitable for demanding electrochemical, catalytic, and mechanical applications. Industries including electronics, chemical processing, and renewable energy integrate nickel disks into electrodes, catalysts, and contact elements. Notable uses include serving as substrates in electroplating, base layers for thin-film deposition, and reaction surfaces in hydrogen evolution and fuel cell systems. In research, nickel disks are used for surface modification studies, catalyst testing, and electrochemical performance evaluation, enabling breakthroughs in energy storage, water splitting, and coating technologies. Their reliability under diverse operational conditions solidifies their importance in both experimental and production environments.
