It is basically a bare aluminum surface that will oxidize (forms aluminum oxide) as it is exposed to air. The aluminum oxide appears as a light white powder on the aluminum surface. Anodizing is a process that oxidizes the aluminum in a controlled environment and it creates a very thin very hard surface on the aluminum.

What is the white rust in aluminum alloys composed of?
Apr 30, 2010· The aluminum oxide coating on aluminum is very tenacious as long as it is thin. After it gets thicker, it is subject to fracturing into powder even tho it is nearly as hard as a diamond. Rust on iron is iron oxide, and it requires water to form and it is NOT an hydroxide.
Why has white powder formed on metal parts after cleaning
I just cleaned much of my engine compartment with Abro Heavy Duty Degreaser, and I noticed that on certain metal parts like the valve cover, thermostat housing and transmission housing a white powder has formed:. I left the degreaser on for maybe 30 seconds to a minute, and in some cases agitated it with a brush, then pretty thouroghly rinsed it with a water hose.
