  • Type of Metal???

    I am restoring a 1981 Yamaha 850 and wish to plate some of the parts. I plan to use Electroless Krome. My biggest concern is not knowing what type of metal the parts are made of and ruining a batch of electroless krome solution. The Aluminun parts can be zincated and then plated with electroless krome, correct? Is it safe to assume that if a part is not alluminum and does not react to acid, then that part can be safely put in the electroless krome solution? If a part reacts to acid is it safe to then flash copper? I have read much of the forum and everyone speaks of the reaction of acid to pot metal, zinc, etc. If using muriatic acid how quick will this reaction be? I plan to puchase the flash copper and electroless krome kits. Any help would be greatly appreciated

    One more question?

    Can any metal that reacts to acid be placed in the Pot Metal Electroless Nickel solution? Thank You

      Yes, aluminum can be zincated then plated with Electroless Krome (or Flash Copper if desired)

      The reaction of zinc die cast/Pot Metal parts to muriatic acid is immediate. It's quite obvious when it occurs. Plating these parts with Flash Copper first will allow you to plate them in E-Krome.

      If it doesn't react to acid, and it's not aluminum, then you should feel fairly safe that you can plate it in the E-Krome, particularly if you're referring to metal parts on your bike.

      If you want to be safe, Flash Copper everything before plating with E-Krome. You'll also benefit by having a nice thick layer of copper, which can easily be polished to a high shine, underneath your Krome plate.
