Car fuel tank cast iron or lead alloy good

Currently, fuel tanks are divided into iron and plastic materials.

1. The main difference between iron and plastic fuel tanks is the production process, and there is little difference in performance/function/quality/safety.

2. Currently, many manufacturers still use iron fuel tanks in their vehicles. There is no evidence or examples to show that iron fuel tanks are more dangerous than plastic fuel tanks.

3. Although iron fuel tanks are heavier than plastic, they are negligible when compared to empty weight and have little or no effect on fuel economy.

Iron and plastic have their own advantages and disadvantages. Plastic blow molding technology has not been mature for a long time, and plastic fuel tanks have only started to be used in recent years. There is no question of which of the two materials is better or worse, and manufacturers generally choose to produce according to their own processes.
