Battery contacts rarely use blackening treatment. This is mainly due to the special needs and working environment of battery contact points.

Firstly, the main function of a Battery Contact is to ensure the stable transmission of current, therefore its conductivity is crucial. Although blackening treatment can enhance the corrosion resistance of metals, it may also affect their conductivity to some extent. In order to ensure good conductivity of battery contact, surface treatment methods that have a smaller impact on conductivity are usually chosen, such as gold plating, silver plating, etc.

Secondly, the working environment of a Battery Contact is usually quite unique, such as requiring it to withstand certain changes in current, voltage, and temperature. These factors may all affect the effectiveness and stability of blackening treatment. By contrast, some more durable surface treatment methods may be more suitable for the usage needs of battery contact.

Finally, the cost of blackening treatment is also one of the factors to consider. Compared to other surface treatment methods, blackening treatment may require more chemicals, equipment, and labor, thereby increasing costs. For large-scale production of Battery Contact, choosing a lower cost and better surface treatment method may be more appropriate.

Therefore, although blackening treatment can improve the corrosion resistance of metals in some cases, it is less commonly used for special parts such as Battery Contact.
