2. Foil (metal) - Wikipedia

   en.wikipedia.org/wiki/Foil_(metal)

   A roll of aluminium foil. A foil is a very thin sheet of metal, typically made by hammering or rolling. [1] [2] Foils are most easily made with malleable metal, such as aluminium, copper, [3] tin, and gold. Foils usually bend under their own weight and can be torn easily. [2]

3. Aluminium foil - Wikipedia

   en.wikipedia.org/wiki/Aluminium_foil

   Aluminium foil (or aluminum foil in American English; occasionally called tin foil) is aluminium prepared in thin metal leaves. The foil is pliable and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.

6. Aluminium - Wikipedia

   en.wikipedia.org/wiki/Aluminium

   Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.

7. Aluminium alloy - Wikipedia

   en.wikipedia.org/wiki/Aluminium_alloy

   Welded aluminium alloy bicycle frame, made in the 1990s. An aluminium alloy (UK/IUPAC) or aluminum alloy (NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc.

8. Metal leaf - Wikipedia

   en.wikipedia.org/wiki/Metal_leaf

   Some metal leaves may look like gold leaf but do not contain any real gold. This type of metal leaf is often referred to as imitation leaf. [3] Metal leaves are usually made of gold (including many alloys), silver, copper, aluminium, brass (sometimes called "Dutch metal" typically 85% Copper and 15% zinc) or palladium, as well as platinum.

9. Aluminium–copper alloys - Wikipedia

   en.wikipedia.org/wiki/Aluminium–copper_alloys

   The starting material is primary aluminium; in contrast to other cast aluminium alloys, secondary aluminium (made from scrap) is not used because it reduces elongation and toughess at break. The AlCu cast alloys are prone to hot cracking and are used in the T4 and T6 hardening states. [14]
