Effective protection against galvanic corrosion

(businesspress24) - Frenzelit GmbH is proud to present novaform

The solution manufactured by Frenzelit is a separating layer that decouples two metal surfaces. Differently alloyed metals always seek potential equalization when they come in contact with one another. Electrons pass from the low-alloyed metal to the high-alloyed metal. The result: The low-alloyed metal corrodes.

Electric vehicles also require reliable protection from galvanic corrosion, especially for separating the rocker panel from the battery module. External influences such as water (road spray during rainy weather) or salt (spread on roads in the winter) can accelerate potential contact corrosion.


Frenzelit developed rings made of parating layer between the high-voltage battery systems required in electric cars and the vehicle body. It prevents the emergence of a conductive connection between the parts to stop corrosion.

One common method of protecting automotive parts from corrosion is sealing them by means of painting, but it may not be sufficient when used on the contact surfaces of two different metals that are present in a vehicle. This type of sealing is the successor to the earlier process of galvanizing the entire body. Another option to prevent corrosion to use something called a sacrificial or reactive anode. As the name suggests, the part active anodes have clear disadvantages: Their use requires more effort and expenditure, because they must be replaced more frequently depending on the size and geometry of the application.

Supplied on a reel: Rings using the kiss-cutting process

In contrast, the Frenzelit part lasts for the entire service life and does not require maintenance. It offers distinct cost and application advantages over established solutions. Another key benefit is the fact that it is supplied on a reel. Supplying the material in bulk would be too impractical for high volumes, as it requires the removal of the release liner from the self-adhesive surface of the part prior to assembly. Instead, Frenzelit delivers the parts on a reel to facilitate assembly. The individual rings are already pre-punched using the kiss-cutting process. This option is also an excellent choice for automated manufacturing processes.
