Vale ‘S’ Nickel Pellets are a sulphur-activated anode material consisting of discrete pellets within the size range 6–14mm. They are normally contained in titanium mesh anode baskets enclosed in a suitable anode bag.
Nickel S Pellets contain a very small amount of sulphur (typically 0.025%) that is deliberately added during the refining process. This makes the pellet easier to dissolve in the electroforming solution and allows higher dissolution currents to be employed.
In addition ‘S’ nickel pellets can be used in chloride-free solutions, a distinct advantage in electroforming due to the lower internal stress levels that can be achieved.
Hart Materials supplies Vale ‘S’ Nickel Pellets in standard 50kg packs although, occasionally, 10kg packs may be available.
