Technical Field

The invention relates to the technical field of kitchen utensils, in particular to a production method of a titanium-aluminum composite material pot.

Background

The traditional cooker is mostly made of aluminum alloy, and the bottom of the traditional cooker is ground or turned, so that negative effects are brought, for example, when the aluminum alloy cooker bottom is easy to oxidize and heat, due to the fact that the bottom of the aluminum alloy cooker bottom is small in thickness, the aluminum alloy cooker bottom cannot be fully heat-absorbed, a large amount of heat energy is lost, and after the aluminum alloy cooker bottom is used on an electromagnetic cooker, the aluminum alloy cooker bottom cannot be partially magnetically conducted or is low in magnetic conduction efficiency. Along with the development of society and the improvement of living standard of people, the requirements of people on cookers are higher and higher, and the traditional design and production process can not meet the requirements of people more and more.
