Can copper and aluminum touch? The primary metals of concern in terms of galvanic corrosion contact with copper are aluminum and zinc. Large differences in the thermal expansion rate between copper and these metals may cause additional problems. Also avoid using copper and some brass fasteners with aluminum, zinc and most ferrous metal.
Can aluminum be in contact with copper? Theoretically, the aluminum will galvanically corrode near the area where it’s connected to copper when it’s wet. But it’s not a critical application like on an airplane, and rainwater is not highly conductive.
What metals can touch aluminum? With a thick enough coating, even a very reactive metal like brass can be used on an aluminum structure without corrosion. Since stainless steel remains one of the least reactive metals without coating, it’s smarter to use it as the base material.
Can a copper wire and an aluminum wire of the same length? Can a copper wire and an aluminum wire of the same length have the same resistance? Explain. Yes. … If the lengths of the wires are the same, then the ratios of resistivity to cross-sectional area of the aluminum is also larger by the same proportion, the two wires will have the same resistance.
