Is nickel silver magnetic?

Nickel silver is actually a copper alloy but silver in color. Our nickel silver is a mixture of 55% copper, 27% zinc and 18% nickel - the zinc and nickel components give it a silver color. Because this material is still a copper-based product, it can be engraved and will oxidize black. Nickel silver is not magnetic.

What is fine grain silver?

Fine-grain silver is defined as a silver alloy with an addition of 0.15 wt% of nickel. Silver and nickel are not soluble in each other in solid form. In liquid silver only a small amount of nickel is soluble. During solidification of the melt this nickel addition gets finely dispersed in the silver matrix and eliminates the pronounce coarse grain growth after prolonged influence of elevated temperatures. Fine-grain silver has almost the same chemical corrosion resistance as fine silver. Compared to pure silver it exhibits a slightly increased hardness and tensile strength. The electrical conductivity is just slightly decreased by this low nickel addition. Because of its significantly improved contact properties fine grain silver has replaced pure silver in many applications.

What are PM parts made of?

Next to bronze bearings, nickel silvers along with brasses are the most widely used materials for structural PM parts. Typical applications include hardware for latch bolts and cylinders for locks and shutter components for cameras; gears, cams, and actuator bars in timing assemblies and in small generator drive assemblies; and decorative trims and medallions. In many of these applications, corrosion resistance, wear resistance, and artistic appearance play important roles.

How to remove oxide from metal?

In electroplating, the oxide layer can be removed by chemical or electrolytic treatments just prior to insertion into the electroplating bath. Such activation is used for plating nickel-on-nickel, chrome-on-chrome, gold-on-nickel, silver-on-nickel, and nickel-on-Kovar™. For example, acid cleaning of nickel can be accomplished by the immersion of the nickel surface into an acid bath (20 pct by volume sulfuric acid) followed by rapid transferring through the rinse into the deposition tank. The part is kept wet at all times to minimize re-oxidation.
