Copper-aluminum washers – reliable connections

Copper-aluminum washers ACP 10-1/50 are specialized mounting elements designed to connect copper and aluminum wires. Their main task is to eliminate galvanic corrosion, which occurs due to the direct contact of these two metals. This corrosion can lead to a deterioration of conductivity and, consequently, to a failure of the electrical installation. Using these washers ensures stable and safe connections, resistant to external factors and long-term use.

Construction and application

ACP 10-1/50 washers are made of a bimetallic material – a combination of copper (CuZn40Pb2 / CW617N) and aluminum. This construction creates a transition layer that prevents current flow between different metals, minimizing the risk of corrosion. They are designed for metric screws size 10 mm (M10) and are characterized by precise dimensions: inner diameter 11 mm, outer diameter 21 mm and thickness 1 mm. This ensures a perfect fit and even pressure distribution.

Benefits of use

• Protection against corrosion: Eliminate galvanic corrosion, extending the life of the electrical installation.
• Connection stability: Provide durable and reliable connections of copper and aluminum wires.
• Versatility: Designed for metric screws M10, making them compatible with a wide range of applications.
• High conductivity: Materials used in production ensure good electrical conductivity.
• Convenient packaging: The package contains 50 washers, which is economical for both professionals and home users.
• Simple assembly: Do not require special tools or assembly skills – just place the washer between the connected elements.
• Raw state: Lack of protective coatings ensures optimal electrical conductivity and minimizes the risk of chemical substances affecting the connection.

These washers are used in electrical installations of residential and industrial buildings, photovoltaic systems and everywhere where it is necessary to connect copper wires with aluminum in a safe and durable way. They are particularly recommended in places exposed to moisture or corrosion.
