Aluminum bimetallic washer – protection against corrosion and durable connection

The ACP 6-1/50 bimetallic washer is a fastening element designed to connect components made of copper and aluminum. Its main function is to eliminate the phenomenon of galvanic cells forming at the interface of these two metals, which prevents corrosion and ensures long-term connection reliability. This is particularly important in electrical installations, where the potential difference between copper and aluminum can lead to rapid degradation of components.

Construction and materials

The washer is made of a combination of copper (CuZn40Pb2 – CW617N) and aluminum, which is key to its effectiveness. Copper provides good electrical conductivity, while aluminum provides lightness and corrosion resistance. The washer thickness is 1 mm, and the outer diameter is 13 mm. The inner diameter of the washer is 6.5 mm, making it ideal for metric screws size 6. The raw surface finish provides good mechanical properties and the possibility of further processing if required.

Applications and benefits

• Elimination of galvanic cells: Prevents corrosion at the interface of aluminum and copper, extending the life of the connection.
• Durable connection: Provides a stable and reliable connection of components made of different metals.
• Versatility: Suitable for use in various electrical and mechanical installations where an aluminum and copper connection exists.
• Appropriate size: Designed for metric screws M6, making it easy to select the appropriate fastening element.
• Easy installation: Simple construction facilitates quick and efficient installation.

ACP bimetallic washers are particularly recommended in places exposed to moisture or corrosive agents, such as outdoor installations or industrial environments. Their use translates into increased safety and reliability of the entire installation and reduced costs associated with repairs and replacement of damaged components.
