Most wood-burning stoves today are made of sheet iron. It is simply not true that cast iron is more durable than sheet iron. Here at HWAM, we have been working with sheet iron for more than 30 years, and we know what advantages it provides for our customers. Sheet iron gives the opportunity to make designs that are not possible with cast iron.
Its smooth surface gives the wood-burning stove the same finish as other pieces of furniture in the house. Furthermore, sheet iron begins to radiate heat upon lighting the stove. The melting point of sheet iron is 1,600 degrees, while that of cast iron is only 1,200 degrees. Cast iron can also crack if heated too quickly, which is impossible with sheet iron.
