There are four types of non-stick pan materials: iron, aluminum, stainless steel and alloy steel.
1. There are two types of iron products: pig iron and wrought iron. Pig iron products are cast, thick and heavy, but have a large heat capacity and are not easy to overheat; wrought iron products are thinner and have a small heat capacity. Both have the defects of being easy to rust and easy to be corroded by acid and alkali, so the life span is shorter.
2. The advantages of aluminum products are light weight and fast heat conduction, but the disadvantage is that they will have a chemical effect with foods with strong acid and alkalinity and shorten the service life.
3. Stainless steel products have the advantages of acid and alkali resistance, no rust, high temperature resistance, not easy to oxidize, and long service life, but the price is more expensive.
4. Alloy products generally also have the properties of stainless steel, but the price is higher.
