Some common problems that can occur with die-cast aluminum pans include:

1. Deformation or discoloration: Due to the high thermal conductivity of aluminum, the pot may be deformed or discolored due to high temperature or sudden changes in temperature during use.

2. Surface wear: Prolonged use or improper use may cause wear on the surface of the pot, especially if metal tableware or knives are used to wipe the aluminum pot.

3. Food sticking: Without proper coating or regular maintenance, food may stick to aluminum pans, making cleaning difficult.

4. The bottom of the pot is dented: Prolonged use or collision may cause the bottom of the aluminum pot to be dented, which may affect the heat conduction performance.

5. Coating wear: Some aluminum pots are coated to prevent food from sticking, but long-term use or improper use may cause the coating to wear and need to be replaced regularly.

6. Metal migration: Low-quality or substandard aluminum pots may have metal migration problems, releasing metal elements such as aluminum into food, which may affect health.

7. Oil and water leakage: There may be quality problems in the welding joints of some aluminum pots, resulting in oil and water leakage.

To avoid these problems, it is very important to choose a high-quality aluminum pot and follow correct usage and maintenance methods.
