Silver has the best electrical and thermal conductivity of metals. The electrolytic silver coating is very well suited for objects or objects which, in addition to the above-mentioned properties, require better corrosion resistance than, for example, copper. Silver is a highly solderable metal and also has antibacterial properties.
Silver plating is the right choice when the coating is desired to have good electrical conductivity, reflectivity (visible light and IR reflection) or to improve the appearance of the product for decorative purposes.
Silver tends to form sulfides and oxides that cause the silver surface to darken. Rhodium coating can prevent / inhibit this reaction.
