Is the wok in the restaurant made of pig iron or wrought iron?

According to Baidu, the wok in the restaurant is made of wrought iron, with fine workmanship, thinner wall, better heat conduction effect and faster cooking speed.

In China and Southeast Asia, the pot is a cooking tool. It is characterized by a large opening at the top and a round bottom. Because the food in the south of China is mainly cooking, the handle of the wok is designed for the convenience of cooking.
