Why Do Heavy-duty Connectors Corrode? How Can We Avoid Corrosion?

24 pin heavy duty connectorWhy does corrosion occur? 4 pin heavy duty connector is 6 pin heavy duty connector used by many manufacturing companies in the industrial production process. The frequency is also very high. At the same time, different corrosion conditions will definitely occur, and electrochemical corrosion is one of them.
Electrochemical corrosion is the accelerated corrosion caused by the contact of metal or alloy A form with a metal that is more chemically inert in the same electrolyte. In bimetallic contact structures, this form of corrosion is one of the most serious degradation effects. Galvanic corrosion will occur at any time as long as different metals coexist in a solution containing salt ions.
The conditions for electrochemical corrosion are:
1. The materials have different surface potentials 2. Common electrolytes 3. Common current paths
For example, the copper-aluminum connection in connector heavy duty will produce alkaline aluminum hydroxide, which will volatilize hydrogen under the action of electrochemical corrosion, resulting in a serious reduction in contact area and severe corrosion causing mechanical failure. Or in actual applications, we can also find that in screw crimping heavy duty 2 pin connector products, screws and copper contacts are more susceptible to corrosion. An important factor in electrochemical corrosion is humidity. Humidity is the key to the amount of electrolyte. If the electrolyte is not completely exhausted, electrochemical corrosion will not stop. Therefore, in the heavy duty connector 16 pin with bimetallic contact structure, it is more necessary to improve the protection level of the product, or use auxiliary contact elements and transition gaskets (add grease or lubricant) to reduce the impact of humidity on the product.
Therefore, heavy duty connector 5 pin manufacturers and customer groups need to have a professional understanding of electrochemical corrosion in order to achieve better and smoother manufacturing.
