Kitchen foil metal is a term used to describe ALUMINUM, which is an 8 letter word. ALUMINUM is a lightweight, silver-colored metal that is highly malleable and ductile. It is the most abundant metal in the Earth's crust and is widely used in many industries due to its low cost and high strength-to-weight ratio. In the kitchen, ALUMINUM foil is often used to cover food for storage or to line baking pans. It is also used to wrap food for grilling or roasting.
