Abstract

A high-performance composite metallic material used for manufacturing cooking pan or cooker is composed of the 1st stainless steel layer, the 2nd aluminum layer, the 3rd Al-alloy layer, the 4th aluminum layer and the 5th stainless steel (or iron) layer. Its preparing process includes such steps as laminating three aluminum layers, rolling, heat treating, attaching two stainless steel layers, hot rolling and heat treating.

Description

Technical field [0001] The invention belongs to the technical field of metal products, and specifically relates to a high-performance metal composite material and a manufacturing method and application thereof. Background technique [0002] Now domestically produced cookware products (such as woks, etc.) usually use a single material. Because a single material is limited by its inherent physical and chemical characteristics, the pot body material's strong hardness, wear resistance, corrosion resistance, heat transfer, electromagnetic induction performance and surface treatment process are greatly limited. , So that the overall performance of the internal and external performance of the cookware made of a single material is not satisfactory. Many improvement measures have also been proposed. For example, in order to make up for the lack of thermal conductivity of stainless steel materials, a piece of aluminum or copper plate with better thermal conductivity is re-welded on the bot...
