Cast aluminum pressure cookware and stainless 5-ply cookware are both produced by Scanpan. Inside the pots is stainless steel or non-stick. A process that involves melting, molding, and curing reinforces aluminum to make it castable. In comparison to most nonstick cookware made of spun or stamped aluminum, this is much more durable. Heat-resistant Bakelite handles or stainless steel handles are available. Stainless steel, toughened glass, or a glass/stainless mix are available for lids.
