Multi layer composite materials

      Regarding multi-layer composite pots, different composite methods have their own characteristics. 


      The pot made of two-layer steel composite materials, one side is 430 stainless steel, and the other side is 1050 aluminum. This kind of pot has the characteristics of fast heat conduction and light weight. It usually needs to add Teflon coating, because aluminum directly contacts food, sometimes harmful substances will be precipitated. 


      Three-layer steel is composed of 430+aluminum+304 stainless steel. This is the most commonly used composite material with the highest cost performance and the best practicality. 430 stainless steel allows the pot to adapt to any fuel, including gas stoves, induction cookers, etc. 1050 aluminum can increase the heat conduction speed, so that the pot can be heated evenly during cooking, and a smaller fire source can be used to save energy. 304 stainless steel is a safe food contact material. Four-layer steel is usually composed of 430+copper+aluminum+304 stainless steel. 


      The characteristic of four-layer steel is that it conducts heat 1.7 times faster than aluminum, and it also gets rid of the stereotyped color of stainless steel. There are many combinations of five-layer steel,

430+3003 aluminum+1050 aluminum+3003 aluminum+316L stainless steel

430+3003 aluminum+1050 aluminum+3003 aluminum+316Ti stainless steel

Copper+3003 aluminum+1050 aluminum+3003 aluminum+Cu stainless steel

430+3003 aluminum+1050 aluminum+3003 aluminum+Ti

      These, like four-layer steel, are the most high-end kitchenware materials. The price of each finished kitchenware is more than US$100, and it also provides users with a higher level of food safety and a more gorgeous appearance.
