Copper foil is a popular material for radiator fins because it has high thermal conductivity, allowing it to effectively transfer heat from the radiator. Additionally, copper is strong and resistant to corrosion, which makes it ideal for use in automotive applications. Copper foil can be easily shaped and formed into fin shapes, and it can be a cost-effective solution when compared to other materials such as aluminum. Overall, copper foil is a durable and efficient choice for radiator fins.
