Tin metal anodes
What’s Tin Metal AnodeTin metal anodes are used in electroplating. Tin metal anodic plating is a process in which a tin-plated film that can be soldered to the surface of material via an electric current is deposited. Tin electroplating is a very cost-effective process. Tin is readily available and much cheaper than metals such as gold, platinum, and palladium. Tin anodes are usually readily available in most quantities, including bulk, and can be resized according to customer specifications.
Electroplating with a tin metal anodeElectroplating with a tin metal anode immerses the tin anode and the metal part in an electrolyte solution. Then, an electric current is passed through the liquid. Tin is connected to a positively charged anode electrode, and a metal portion is connected to a negatively charged cathode electrode.
- The tin is attracted to the cathode by the DC and dissolved in the electrolyte solution. The melted tin is reduced and attached to the metal part. Several types of electroplating processes can be used for tin anodes.
- For delicate parts, vibrational plating is an expensive method of coating metal parts by placing the components in a basket containing metal buttons filled with electrolytes and vibrating the basket.
- Barrel plating is used for smaller parts by rotating the barrel containing the electrolyte. It is the most cost-effective plating method.
- Rack plating is used for large metal parts, where metal is hung on the rack and immersed in the electrolyte. This process is more expensive than barrel plating and less costly than vibration plating.
