How to prevent copper handles from oxidizing

  The following methods can be taken to prevent the oxidation of copper handles:

  1. Passivation treatment: Copper passivation currently recognized as the most effective method. It forms a protective film on the surface of copper to prevent oxidation. Using a chrome-free type of passivating agent, this pass agent is environmentally friendly, easy to operate, and can effectively resist the erosion of wet-heat salt fog, toxic bacteria, etc., and has good anti-corrosion and electrical properties.

  2. Electroplating: The electroplating process deposits a layer of metal or alloy on the surface of the copper parts through electrochemical methods to a protective layer, preventing the copper handle from contacting with the air and thus preventing oxidation.

  3. Chemical plating: Similar to electroplating, but does not require power source, forming a protective layer on the surface of the copper furniture handle through chemical reactions.

  4. Antioxidants: Use special antioxidants, such as wax or otheratives, coated on the surface of copper, forming a protective layer.

  5. Moisture-proof agent: Place moisture-proof agents, such as silica gel descants, in the storage environment to absorb moisture and reduce the risk of oxidation.

  6. Temperature control: Try to store the copper furniture handle in a stable temperature environment avoiding rapid changes in temperature and humidity.

  For bare copper wire, in addition to the above methods, you can also consider using tin plating and other methods to protect the surface maintain its good electrical conductivity. In industrial applications, using copper passivating agent (such as JYM-106 copper no-chrome passivating agent from Jiayime) is a common method to prevent oxidation of brass handles. This passivating agent is not only easy to operate but also can form a stable protective film on the surface of the furniture handle, effectively preventing oxidation without affecting the conductivity and thermal conductivity of copper.
