Sorted by: 5. The reason is that aluminium carbide, A l X 4 C X 3 is formed. The reaction occurs at around 500°C on the interface. The problem with this substance is that it is brittle, and it also reacts with water: A l X 4 C X 3 + 12 H X 2 O 4 A l ( O H) X 3 + 3 C H X 4. More info at this and this wikipedia page.

Aluminum or Steel: Which Metal is Better? - ErectaStep

WebStainless steel reacts with aluminum in a process called galvanic corrosion. This corrosion occurs when two dissimilar metals are in contact with each other in the presence of an electrolyte, like salt water. When this happens, electricity flows between the two metals, causing corrosion. This article will walk you through galvanic corrosion ... sighclops

WebAluminium and stainless steel together also appears to be a bi-metallic corrosion risk, from the ‘nobility’ table. With this combination the affect of relative surface area on corrosion is important. A large area of ‘cathode’ relative to ‘anode’ will accelerate the anodic corrosion. WebJul 14, 2009 · Re: Galvanic Reaction Between Stainless Steel and Aluminum. 04/06/2007 10:31 AM. Aluminum is sacrificial to both stainless and copper. Anodizing the aluminum and passivating the stainless will slow down the galvanic action, but elimination of moisture at the joint by a secondary coating such as epoxy paint will minimize the moisture/dry cycle ... WebGalvanic corrosion occurs when two dissimilar metals are in contact electrically in the presence of an electrolyte. During this process, corrosion occurs on the anode, whereas the cathode is protected. For example … the preserves apartments sterling heights
