Most aluminium cookware is non-stick but few stainless steel pans are, why?
A. Non-stick coatings adhere well to the soft aluminium but in the past have not adhered so well to the very hard surface of stainless steel. Moreover stainless steel by its nature is very durable and has tended to out live any non-stick coating applied to it. Recently non-stick coatings have improved so we are seeing more and more on stainless steel especially for the milk pans, smaller saucepans and the frying pans.
