We offer NiBRON - a proprietary electroless nickel-boron finish designed to resist fretting and galling wear.

Because gold is a relatively soft metal, it's usually mixed with quantities of silver and other various common metals such as copper to give it more of a hardness. 24 carat gold is almost pure gold 18 carat gold is approximately 75% gold and 25% other less

How to Extract Gold From Electronics: In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straight-forward and pretty easy, but the chemicals

In medical plating applications, sulfamate nickel is typically used as an undercoat for gold or silver when coating flexible electrical contacts. Plating Onto Titanium The fact that so many medical devices are now made from titanium has created a demand for a safe, reliable process for plating onto titanium.

Gold Bulletin 2002 • 35/1 23 Internet communication uses high frequency signals to pass data between users. This requires very good and reliable electrical connections and so gold is used for coating connector pins and for sockets in telecommunications generally.

Silver nanoparticles, generally smaller than 100 nm and contain 20–15,000 silver atoms, have distinct physical, chemical and biological properties compared to their bulk parent materials. The optical, thermal, and catalytic properties of silver nanoparticles are strongly influenced by their size and shape.
