chelation is a type of bonding of ions and molecules to metal ions. it involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central atom. these ligands are called chelants chelators chelating agents or sequestering agents.
i think i've read every post on the web to make sure i was up-to-date on the convetional wisdom on seasoning an aluminum pan. i had a perfectly good and decently seasoned professional aluminum saute pan that a friendly house guest vigorously washed in soap (thanks!).
aluminium alloys. the process where the aluminium is shaped to its required form. this process is used for making the vast majority of aluminium products from spectacle frames telephone bodies aeroplane fuselages or spaceship bodies. the malleability of aluminium means it can be easily rolled into thin sheets.
aluminium atoms easily bind with other metals forming compounds. at the same time it's impossible to isolate aluminium by simply melting down the compounds in a furnace as is the with iron for example. the aluminium production process is much more complex and requires huge amounts of electricity.
read the how does hard anodized aluminum cookware fit into the equation discussion from the chowhound cookware aluminum food community. if i couldn't have copper thick hard-anodized aluminum would be my first choice overall. corrosion resistance mainly comes from the sealing process of the aluminum oxide not the thickness.
aluminum is considered a soft metal but there are alloys of aluminum that respond to heat treatment in a similar manner to steel and other iron based metals. pure aluminum and aluminum alloyed primarily with manganese or magnesium does not respond to heat treatment so this article will focus on the aluminum alloys that contain copper zinc
a simple lemon bath is used to demonstrate this process. lemon juice is a natural acid that attacks the oxidized copper-oxygen bond releasing it from the surface of the pennies. placement of a metal such as an iron nail in the lemon bath containing suspended copper ions results in a simple copper plating of the iron nail.

we perhaps have *hundreds* of threads and *thousands* of posts about seasoning cast iron and carbon steel pans but next to nothing on seasoning aluminum and ss. yet bare unseasoned aluminum and ss are porous like unseasoned ci and can be just as "sticky" (aluminum) if not more so (ss).
