Which is better, aluminum or iron?

Each has its own advantages and disadvantages. The specific choice depends on personal needs and preferences.

1. Aluminum dice have the advantages of good thermal conductivity, light weight and easy processing, so the price is relatively low. However, aluminum products may cause certain harm to human body during long-term use, such as anemia and osteoporosis caused by excessive intake of aluminum ions.

2. Iron seeds are durable, not easy to deform and have a long service life. Iron is one of the essential trace elements for human body, which is beneficial to human body. However, the hammer has poor thermal conductivity and is difficult to process, so the price is relatively high.
