Extended information:

Pressure cookers are divided into three types: aluminum, aluminum alloy and stainless steel.

Three kinds have their own characteristics:

Aluminum is light in weight, fast in heat transfer, cheap in price, and its service life can reach more than 2 years. But using it will undoubtedly increase the absorption of aluminum, and long-term use of it is not good for health.

aluminum alloy products are better than pure aluminum products, which are durable and strong.

Although the stainless steel pressure cooker is expensive, it is heat-resistant, beautiful, difficult to react with acid, alkali and salt in food, and its service life is the longest, which can reach more than 3 years. Therefore, even if you spend more money at a time, you'd better buy a stainless steel one.
