The Impact series is stainless steel cookware, refined with a sandwich base with an aluminium core. The result is solid pots and pans that heat quickly.
Steel is known for its tremendous durability. And who doesn't want hear-wearing cookware!
It is also well-known that aluminium is a far better heat conductor than steel. Therefor, products in the Impact line are constructed with an aluminium base - in fact is it an aluminium plate surrounded by stainless steel, which furthermore makes the series suitable for all cooktops, incl. induction.
