Caswell Electroless Pot Metal Treatment

(Replaces ALZinc Electroless Nickel Kit)

The major problem with Pot Metal (Zinc Die-Casting) is that it corrodes - badly!  Its use is widespread in the automotive and motorcycle industry, mainly because it is easy to cast into intricate parts. Unfortunately, the metal is easily subjected to corrosion, particularly by mild acid attack.  The zinc readily degenerates in the presence of even a mild acid such as tomato ketchup.

Pot Metal will polish up and look very good, for about 2-3 days, then it rapidly dulls down to a leaden look. This can be most unattractive on vehicles with lots of shiny aluminium or chrome. By polishing the part, then immediately plating it with Pot Metal Electroless Nickel, the metal can be given a long term, bright, shiny surface, closely matching the other components on the vehicle.

Parts made of Pot Metal and treated with Pot Metal TREATMENT may be plated with any of the following CASWELL Plating Systems:- Electroless Nickel, Electroless Krome, Regular Nickel (using power and anodes), Copy Chrome, Copper.

The Pot Metal TREATMENT system also provides a thin layer of nickel all over the surface, to prevent the acidic action of nickel, copper & Electroless Nickel & Krome baths, from attacking the pot metal.  Repairs can be carried out before this process, if soldering, or afterwards if copper plating.

It is important that you ensure all areas of the part are extremely clean, especially any pitted areas. These should be closely examined for any black deposits, and they should be removed by drilling, bead blasting etc. In the event that the part will require some repair, this may be carried out with lead free "Solder pastes", or by heavily copper plating and then sanding smooth.
