Is alum conductive
Web1 mrt. 2024 · Suppose I connect a conductive wire (cross section 1 mm $^2$) to an aluminum object. Since aluminum is highly conductive, electricity will flow smoothly inside the object with little resistance. However, since aluminum is also very reactive, there is a thin layer of highly resistive aluminum oxide on the surface of the object. WebAluminum is highly conductive by itself; however, the oxide layer has physical and chemical properties resembling a ceramic. One of the principal characteristics of ceramics is electrical insulation.
