Although aluminum also oxidizes quickly, the thin aluminum oxide (sapphire) layer is transparent, and so the high-reflectivity underlying aluminum stays visible. In modern aluminum silvering, a sheet of glass is placed in a vacuum chamber with electrically heated nichrome coils that can evaporate aluminum.Silver Plating Aluminum: Silver plating of aluminum offers outstanding surface conductivity and corrosion resistance for critical applications within the power transmission/distribution and energy markets. Silver offers good solderability and excellent lubricity and anti-galling in high temperature applications Plating aluminum is a specific subset of plating that is complicated by the fact that aluminum rapidly oxidizes when exposed oxygen to present in the atmosphere.
