Why Do You Use Cast Aluminum?

Swiss Diamond

Swiss Diamond cookware, with the exception of the HD Pro Stainless Steel line, is made purely of cast aluminum with a high-quality nonstick coating. Aluminum is ideal for making cookware because it is lightweight, corrosion resistant, and has excellent thermal conductivity. There are two main methods of creating the aluminum bodies used in cookware today:

Stamped or Spun Aluminum - While quick and economical, these methods allow the pan to warp over time. Stamped aluminum cookware is produced when a large sheet of aluminum is forcefully pressed against cookware-shaped form. Spun aluminum cookware starts with the same thin sheet of aluminum, but instead of being pressed, it is stretched and shaped around a cookware-shaped form using a spinning lathe. Both methods transform a flat sheet of aluminum into the shape of a piece of cookware, but since the metal's "natural" or original shape was a flat sheet, the metal can warp when repeatedly heated and cooled. This video from the Discovery Channel shows the production process of a stamped aluminum skillet - "How It's Made: Professional Cookware."

Cast Aluminum - Swiss Diamond cookware is made using cast aluminum. The metal is melted to a liquid state and then poured into cookware-shaped molds. Once the metal is cured and cooled, it is removed from the mold and has the shape of the form. This is a more expensive and time-consuming method, but also produces a higher-quality product. Swiss Diamond products will never warp, even if taken straight off the stove and placed under cold running water. The cast aluminum also provides even heat distribution with no hot spots for a lifetime of superior performance.
