What is the difference between aluminum foil facing and other types of metal foil facing?

Aluminum foil facing is distinct from other metal foil facings due to its unique properties. It is lightweight, highly reflective, and offers excellent heat resistance. It's also non-toxic and has good barrier properties against oxygen and moisture, making it ideal for food packaging and insulation. Other metal foils, such as copper or stainless steel, may have different thermal or electrical conductivity properties, and are often heavier and less flexible. Copper, for instance, has higher electrical conductivity but is less common in foil applications due to cost and weight. Stainless steel foils are more durable and corrosion-resistant but are not as reflective or lightweight as aluminum. Each type of metal foil has specific applications based on its unique characteristics.
