Galvano Aluminium is an extremely interesting problem-solver for electrotechnical applications thanks to properties such as:

- Low specific resistance of 2,7·10-² Ωcm
- High ductility combined with excellent adhesion
- Ultrasonic welding
- Low specific weight
- The option of producing insulation layers using anodised oxidation.
- Excellent corrosion resistance

Below are examples where Galvano Aluminium assists in solving problems:

Weight Savings for Electricity Transmission

The low specific weight of aluminium allows electricity to be transported at a lower weight than copper. , The aluminium conductor is half the weight of the copper conductor with the same electrical resistance. However, copper connection parts have to be used for technical reasons. Coating the copper connection parts with Galvano Aluminium reliably prevents the contact corrosion between the aluminium conductor and the connection part.

Corrosion Protection of Flexible Copper Conductors

Unstressed copper is extremely ductile. Galvano Aluminium is used to prevent contact corrosion when copper conductors come in contact with aluminium parts.

Temperature-Resistant, Electrical Insulation

For applications which require electricity to be transmitted at high temperatures and the live copper conductor to be electrically insulated, a Galvano Aluminium layer is subject to anodic oxidation to apply an extremely temperature-resistant insulation around the copper conductor.

Ultrasonic Weld Joints

Due to the excellent adhesion of the Galvano Aluminium layer, coated parts can be easily ultrasonic welded.

Low Hydrogen Content with NMR Applications

When the task is to detect the level of hydrogen in nuclear magnetic resonance (NMR) applications, the sensor's hydrogen content is also calculated in the measurement result and distorts the end result. Sensor wires coated with anodised Galvano Aluminium contain considerably fewer hydrogen atoms than wires coated with an insulation paint comprising hydrocarbon compounds.

Optimum Contact of Two Contact Parts with Geometrical Deviations

If two parts are to be electrically connected together, the area of contact between the two parts is of key importance in determining the quality of the connection. The larger the contact area, the lower the current density at the point of contact is and the lower the probability that the electrical connection fails. The ductile Galvano Aluminium layer serves to compensate the surface deviations between the two contact parts. At the same time, this improves the transfer of heat.
