Cobalt Sulphamate — Nickel-Cobalt Electroforming Additive
Also known as: Cobalt Sulfamate
Overview
Cobalt Sulphamate — Product Overview
Cobalt Sulphamate (also known as Cobalt Sulfamate) is added to Nickel Sulphamate baths to increase deposit hardness through nickel-cobalt co-deposition. Shriji Chemicals® supplies high-purity Cobalt Sulphamate that raises Vickers hardness to significantly higher hardness, significantly improving levelling and brightness while maintaining low internal stress — making it the standard choice for security printing, hologram tooling, and precision mould applications across India.
Applications
Where Cobalt Sulphamate is Used
Security Hologram Shims
Cobalt addition hardens holographic shims for longer tool life and sharper definition.
Banknote Printing Cylinders
Harder nickel-cobalt deposits extend cylinder life in high-speed banknote printing presses.
Precision Tooling & Moulds
Used where maximum deposit hardness is required alongside low internal stress.
SIM Card Punch Tools
Harder deposits from nickel-cobalt baths improve punch tool longevity.
FAQ
Common Questions about Cobalt Sulphamate
How much Cobalt Sulphamate do I add to my Nickel Sulphamate bath?
Typically As per target hardness — contact us for guidance, depending on target hardness. Contact us for specific bath chemistry guidance.
Does Cobalt Sulphamate affect internal stress?
At low concentrations (under recommended concentration), internal stress remains low. Higher concentrations increase hardness but may slightly increase tensile stress — bath monitoring is recommended.
Is Cobalt Sulphamate compatible with all Nickel Sulphamate baths?
Yes — it is designed as a direct additive to standard Nickel Sulphamate electroforming baths.
