LAMINATED COPPER ARTICLE OF COOKWARE

摘要

A process of brazing is used to bond copper and stainless steel preformed vessels to form laminated cookware. The process includes an ironing step that is carried out after brazing, in part to improve the integrity of the bond. The ironing step also provides a means to reduce the thickness of the copper in the upright wall portion of the vessel. This yields a lighter weight article of cookware, as compared to one formed from a pre-laminated sheet of copper and stainless steel layers.
