| 摘要 |
The invention relates to a plate-shaped composite material of several metal layers ( 1, 2, 3 ) for producing cookware suitable for induction stoves by deep drawing, wherein the composite material comprises two metallic outer layers ( 1, 2 ) and at least one metallic core layer ( 3 ) arranged between the outer layers ( 1, 2 ), wherein at least one of the two outer layers ( 1 ) is formed of aluminum or an aluminum alloy and the core layer ( 3 ) adjacent to this outer layer is formed of a ferromagnetic metal or a ferromagnetic metal alloy. The composite material composed in such a way can be coated on the outer layer which consists of aluminum or an aluminum alloy in a simple and cost efficient way. By this it becomes possible to produce high-quality cookware suitable for induction stoves with a desired coating at low cost.
