The plating thickness for decorative rhodium platings used by jewelry manufacturer can range from .05 microns to 1.5 microns. For most decorative applications, a thickness from .10 microns to .50 microns are utilized for maintaining long term "brightness". Industrial platings for specialized applications may utilize thicknesses up to 5.0 microns. However, rhodium finishes above 2.

No, as a rule the electroplating process does not hide surface imperfections. In fact, due to the diffusive reflection of incidental light rays, pre-existing cosmetic imperfections are even more noticeable on a brightly plated surface! For best results the item should be polished to the desired level of brightness prior to rhodium plating.

Yes... Rhodium is a thin coating placed on silver, white gold, and platinum jewelry to give it a high polish finish. Dust and contaminants in the environment interact with body oils, lotions, etc to form an abrasive mixture that begins to wear away at rhodium and plated jewelry. Removing these contaminants can significantly extend rhodium life.

Typically, White, Natural, Oak, Cherry and Black. Please refer to Model & Color Code on the Product pages.

Rhodium is a member of the platinum metals group; the other members include platinum, palladium, ruthenium, iridium, and osmium.

Currently, SnPb surface plating is used on several external and internal components. The Pb-Free substitute will depend on the process of manufacturing those components, along with availability in the marketplace. Among the proposed choices currently under consideration are: Mini-Circuits may continue to offer the current SnPb (Tin/Lead) plated products for customers that require the Pb containing materials and are not ready to accept Pb-Free products at this time.

Re-plating is renewing the surface of your item with the appropriate metal, silver, gold, pewter, brass, through an electromagnetic process.

NBP's Econo Black - NBP's own formulations - This molybdate black goes directly on zinc die cast. After the molybdate coating is applied, the parts are submerged in a seal composed of chromates and phosphates that enhance the salt spray resistance of the coating. An organic coating, water dip lacquer, is applied as a final coat to protect the finish and improve appearance.

There are many problems associated with tin plating. One of which is whiskering, like cadmium and zinc, thin needle-like crystals known as "whiskers" form within a period after plating that may vary from a few weeks to several years. A whisker may measure up to .0001" (2.5um) in diameter, and grow spontaneously to a length of 0.375" (10 mm). Conditions that tend to promote the growth of whiskers are compressive stresses and uniform temperatures for long periods of time.

Regarding plating: Plating is not only cosmetic but it protects you from the very slight chance of brass poisoning. Our metal JodyJazz mouthpieces are made from a solid bar of brass. Then there are three layers of plating starting with Copper then Silver or Nickel and then the Gold. We use heavy Gold in 24kts. Over the long run the top layer of Gold can start to wear off. You are still protected from brass poisoning by the other two layers, which will not wear off.

Rhodium was first isolated in 1803 by English chemist William Wollaston. Due to the distinctive red color of the dissolved rhodium compounds, Wollaston named the new metal Rhodium based on the Greek word rhodon meaning "rose".

Initially, exterior trim tapes are offered in 1.1 mm thickness and sealing tapes in 1.2 mm thickness.

Yes. We do white color plating such as Silver, Fake Rhodium or Rhodium plating as desired by you. We can also supply our products with bicolor plating. Our Silver plated bangles that match the White Gold color are very popular.

With the exception of zinc plated parts, all zinc die-castings are processed as follows: preclean, mill, copper strike, and copper plate. Preclean: A two step process to remove most synthetic, petroleum, vegetable, and animal based fluids used in die-casting and machining operations. Mill: A controlled removal of the outer layer of die-cast. This process can remove flash, surface die-cast blisters, and modify dimensions if necessary.

It is not possible to calculate the life of the plating as it depends on various factors such as usage, climatic conditions like humidity and wear and tear. As a result, we cannot guarantee the plating life for any period of time. However we do guarantee the thickness of the plating. Our normal plating thickness for the various items, is as stated in the quick reference chart below, but we can manufacture and plate to any thickness of gold you prefer, if you can guarantee large volumes.

We give a base coat of Copper and then a top coat of Gold, Silver or Rhodium as you specify. The plating is hard acid Gold plating and is durable as opposed to the usual alkaline plating. Our electroplating facility is ISO 9002 certified by KEMA of Netherlands and is state of the art. For our U.S. customers, we generally plate 14 Karat color, but we can also match any color sample provided by you, with a 100% color match guarantee when you provide us the sample.
