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 shorter time.
2. Ceramic electric kettle
It 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, and think that glass should not be heated. The glass here refers to a special high-temperature resistant kettle, such as a 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.
