Using 99.99% Pure Silver material for stamping and forming, and then electroplating a layer of gold on Pure Silver Cup electrodes, Reusable Pure Silver Gold Cup electrodes can prevent Pure Silver from oxidizing in the air and solve the problem of unsightly surface of the product before use.
Although our company can produce this Reusable Pure Silver Gold Cup electrode, we do not recommend it to customers. Therefore, 99.99% Pure Silver Cup electrodes rely on the material itself to collect signals and resist corrosion, which is the best. The only drawback is that Pure Silver will oxidize on the surface in the air, and its appearance will not be particularly beautiful before use. This surface oxidation is normal and will not have any effect on the collected signals. After adding conductive paste and using it several times, the conductive paste will corrode the surface oxide layer, and Pure Silver Cup electrodes will be particularly white and beautiful. Electroplating another layer of gold on the surface of Pure Silver Cup electrodes is only to prevent oxidation. The product looks more beautiful before use, increasing its appearance. Cost, there are no other advantages. And, when the product is used in the later stage, the plating will still peel off.

All conductive pastes on the international market are corrosive to metals. Reusable Pure Silver Gold Cup electrodes are not very beautiful before use, but after long-term use, the plating layer will partially peel off, making the product very unsightly.
Any electroplating layer will partially peel off after long-term use. The attached image shows the partial peeling of the electroplating layer on Reusable Pure Silver Gold Cup electrodes after one year of use in the hospital.

Advantages: Plated with a layer of gold, it will not oxidize and will have a beautiful surface before use.
Disadvantages: One layer of gold plating is applied, which is more expensive than 99.99% Pure Silver Cup electrodes. After long-term use, the plating layer may partially peel off, resulting in a very unsightly appearance.
