Final answer:
Metal chimney flue liners are typically made of stainless steel or aluminum, providing durability and resisting high temperatures and corrosion.
Step-by-step explanation:
Metal chimney flue liners are usually made of stainless steel or aluminum. These materials are chosen for their ability to withstand high temperatures and their Corrosion resistance. A chimney liner is essential for the safe operation of a fireplace or wood stove, as it contains the combustion products and directs them outside the home. The efficiency of a heating appliance, such as a wood stove, is improved when it prevents most of the heat from escaping through the chimney, thus the importance of a well-functioning flue liner.
Metal chimney flue liners are usually made of stainless steel or aluminum. Stainless steel is a popular choice because it is durable, resistant to corrosion, and can withstand high temperatures without warping or deforming. Aluminum is also used, although it is not as strong as stainless steel and may require additional support.
