作者: Jackson SystemsMay 05, 2008 working on an old GE RTU that I did a compressor replacement on and the line going from the roto lock fitting into the evaporator coil broke loose. Was wondering if any one had any insite on repairing the copper line going to the aluminum coil. If it was just copper I could braze it but being copper to aluminum poses a tricky situation. Any help would be greatly appreciated. thanks in
Feb 17, 2018 Carefully observe the figure above. Note that inner surface of bimetallic is of copper while outer surface is of aluminium. Above bimetallic is used for connecting the Current Transformer Primary (connectors made of copper) to the aluminium made bus. While making connection, copper side of bimetallic is mate with copper side of bimetallic and aluminium side with outer face of bimetallic.

Jan 30, 2018 THE WIRE WORKS, THE CONNECTIONS ARE THE PROBLEM Aluminum wire does a good job of conducting electricity (although you do have to use one size larger wire than copper for the same electrical load) and can do the same job for less money. So for a short while it was used in houses for regular wiring. Then the "aluminum wiring crisis" came along, which actually had less to do with
Aluminum wire became popular in the 1970s because it conducts electricity well and is less expensive than copper. It quickly lost its popularity went it was deemed responsible for a large volume of home electrical fires. The problem was that the aluminum connections expanded and contracted much greater than copper.

Alibaba offers 2,589 copper and aluminum connection pipe products. A wide variety of copper and aluminum connection pipe options are available
When copper and aluminum are brought into direct contact in the presence of moisture, a strong galvanic reaction takes place due to the dissimilar properties of the metals. Therefore aluminum connectors cannot be used with copper conductors unless an interface material which is more compatible with both copper and aluminum is present - such as tin.
Reduction connectors are often used in network repairs – more specifically in the production of non-tension connections for aluminium conductors in accordance with DIN EN 60228, and copper conductors in accordance with DIN EN 60228. The connectors are made of two components: aluminium parts (E-Al) and copper parts (pursuant to EN 13600).

Sep 24, 2021 2001. A. Aluminum will be very susceptible to galvanic corrosion in contact with copper, assuming that the two metals are also in contact with a common electrolyte (such as water with some ionic content.) Almost any text or handbook on corrosion will have galvanic series table. The farther two metals or alloys are separated on the table, faster the corrosion of the less noble of the two will ...
Sep 21, 2015 Another compliant option is the King AlumiConn, which can connect both aluminum to copper and aluminum to aluminum. These require a precise torquing of the screw connectors. Depending on the wire going to your light, you might have to pigtail copper to aluminum in the above manner and then wirenut the new copper to the light.
