Electrochemistry Gold Plating Chain with 50 Microns

[MartinMartinez]

Good evening.

I were interested in Chain with VERY thin Gold Plated on the Surface.

So i contacted with Jeweler's shop in China and they told me that they can do Chain of Stainless steel with 50 MICRONS of Thickness. I need that chain that Support scratches without going the gold.

My question is 50 Microns of Gold Plated in One chain is too much right?

Does it possible to do or its just a scam?

Thanks!

There are gold plating baths that will deposit 50 microns (.002"). That's about $33 worth of gold per square inch at that thickness. However, that much thickness is overkill in my opinion. Also, it is probably plated from an alkaline cyanide solution and is pure and quite soft. If you want some hardness at that thickness, it is best to use a sulfite bath.

You would probably be better off plating 2.5 to 4 microns thick from a cobalt or nickel hardened acid gold bath. This is the same bath used to plate wear surfaces on electronic parts, such as fingers or pins (plated about .75 microns thick). The deposit from this type of bath is stressed and can crack if used for very thick deposits (in your case, 50 microns). However, it would work quite well at 3-4 microns, or a little thicker. It will wear very well compared to most other types of deposits. High quality, longer lasting jewelry is commonly plated with a minimum of 2.5 microns of gold.

They tell me that the Price for 50 microns and the Chain is 15 Usd,So its probably has maximum 4-5 Microns Right,.

It sounds like there is some misunderstanding or the wrong use of terms. Some use the term microns when they should have said microinches. 50 microinches is 1.25 microns. That sounds more reasonable for the price.
