What material is good for the kettle?

1, stainless steel electric kettle, the main element of 304 stainless steel is Cr, and only when the Cr content reaches a certain value can the steel have corrosion resistance. Therefore, the general Cr content of 304 stainless steel is above 13%. Not easy to rust, better than iron, harder and cheaper than ceramics, glass and pure copper in hardness and price; In terms of heating time, stainless steel has good thermal conductivity and needs short time; In terms of filtration performance, it has good filtration performance and fast filtration speed, and can filter scale faster and purify water quality. So the use of stainless steel electric kettle can be assured. In addition, when choosing stainless steel electric kettle, you should also make a good choice, and don't choose some cheap steel.

2. The ceramic electric kettle gives us the impression that it is as fragile as a cup, but it has gradually entered the consumer's field of vision and become more and more popular because of its beautiful, healthy, non-toxic and environmentally friendly characteristics.

3, glass electric kettle, many people may not have heard of it, think that glass should not be heated, the glass here refers to a special high temperature resistant kettle, such as high boron silicon electric kettle. Its advantage is that high-temperature heating will not produce any chemicals harmful to the body, and the cleanliness of water can be seen after boiling, and the boiling process can be seen intuitively.

4, copper pot. As for the copper pot, opinions vary. With the changes of the times, it is difficult to buy pure copper pots in the market now. Gradually, there are fewer and fewer copper pots on the market, which gradually fades out of people's sight.

5, silver pot. Maybe everyone has heard of it, but it's really expensive and exclusive to local tyrants. The thermal conductivity of silver is the most prominent of all metals. It can quickly dissipate the heat of blood vessels, so it can effectively prevent various cardiovascular diseases. Pure gold and pure silver have stable chemical properties, are not easy to react with other substances and are non-toxic. The water boiled with it is very soft. This is a good choice for people who especially pursue the quality of life.

When the plastic kettle first appeared, it was loved by a group of people because it boiled water quickly and was cheap. Gradually, the smell of plastic produced by heating is unacceptable and harmful to human body. For health reasons, people seldom use it now.
