Cast aluminum cookware is aluminum cookware that has been manufactured by injecting molten metal into a metal mold under substantial pressure. Most cast aluminum cookware has been die casted where rapid injection and rapid solidification under high pressure combine to produce a dense, fine-grain surface cookware with excellent wear properties.
Cast Aluminum Cookware - Why Use Cast Aluminum Cookware?
Aluminum conducts heat better than any other type of metal (except copper) used in making cookware. Aluminum cookware can be manufactured by using a pressing process or a casting process. Most cookware is made by the pressing process. Casting of aluminum is slower and more expensive than pressing of aluminum, however the casting process results in a thicker pan body. The thicker walls provide better heat retention. Also, during the casting process the bottom of the pan can be made thicker than the walls which helps prevent warping. Cast aluminum is also more porous than pressed aluminum, which also results in better heat retention. Cookware that has been casted will be described as cast cookware. Pressed cookware will normally not refer to the pressing process.
