Aluminium foil (or aluminum foil) is aluminium prepared in thin metal leaves with a thickness less than 0.2 millimetres (8 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.In the United States, foils are commonly gauged in thousandths of an inch or mils. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). Thefoil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimeslaminated to other materials such as plastics or paper to make them more useful. Aluminium foil supplantedtin foil in the mid 20th century.
Annual production of aluminium foil was approximately 800,000 tonnes (880,000 tons) in Europe and 600,000 tonnes (660,000 tons) in the U.S. in 2003. Approximately 75% of aluminium foil is used for packaging offoods, cosmetics, and chemical products, and 25% used for industrial applications (e.g. thermal insulation, cables and electronics).
In North America, aluminium foil is known as aluminum foil. It was popularized by Reynolds Metals, the leading manufacturer in North America. In the United Kingdom and United States it is, informally, widely called tin foil, for historical reasons (similar to how aluminum cans are often still called "tin cans").Metallised films are sometimes mistaken for aluminium foil, but are actually polymer films coated with a thin layer of aluminium. In Australia, aluminium foil is widely called alfoil.

- Q:How do aluminum coils contribute to the fire resistance of products?
- Aluminum coils contribute to the fire resistance of products in several ways. Firstly, aluminum has a high melting point, which means that it can withstand high temperatures before it starts to deform or melt. This property is crucial in preventing the spread of fire as it helps to maintain the structural integrity of the product, limiting the fire's ability to penetrate or weaken it. Additionally, aluminum has excellent thermal conductivity, meaning it can efficiently dissipate heat. This characteristic plays a crucial role in fire resistance as it helps to cool down the surrounding area, minimizing the risk of ignition or combustion of nearby materials. By quickly transferring heat away from the source, aluminum coils can prevent the fire from spreading or escalating. Moreover, aluminum is non-combustible, which means it does not burn or support combustion. This property is vital in fire resistance as it prevents the aluminum coils from adding fuel to the fire. Instead, aluminum acts as a barrier, preventing the flames from reaching other flammable materials and reducing the overall fire hazard. Furthermore, aluminum is resistant to corrosion, which enables the coils to maintain their structural integrity over time, even in high humidity or corrosive environments. This durability is crucial as it ensures that the fire resistance properties of products remain intact, providing long-lasting protection against fire hazards. Overall, aluminum coils contribute to the fire resistance of products through their high melting point, excellent thermal conductivity, non-combustible nature, and resistance to corrosion. These properties work together to limit the spread of fire, dissipate heat efficiently, prevent the addition of fuel to the fire, and maintain the structural integrity of the product, ultimately enhancing its fire resistance capabilities.
- Q:Can aluminum coils be used for insulation purposes?
- No, aluminum coils cannot be used for insulation purposes. Aluminum is a good conductor of heat and electricity, which means it would actually transfer heat rather than insulate it. Insulation materials are typically chosen for their ability to resist heat flow and reduce energy transfer. Materials like fiberglass, foam, or mineral wool are commonly used for insulation purposes as they have low thermal conductivity and can effectively trap air pockets to reduce heat transfer.
- Q:How are aluminum coils inspected for surface defects?
- To ensure the production of high-quality and defect-free aluminum coils, a variety of methods are employed to inspect for surface defects. Visual inspection is one commonly used technique, wherein trained inspectors carefully examine the entire surface of the coils for imperfections such as scratches, dents, or unevenness. This inspection takes place in optimal lighting conditions to ensure visibility and accuracy. In addition to visual inspection, more advanced techniques are utilized to detect subtle surface defects. An example of such a method is fluorescent penetrant inspection, where a fluorescent dye is applied to the coil surface. This dye seeps into any surface defects or cracks, and after a certain period of time, the excess dye is removed. The coil is then examined under ultraviolet light, which causes the dye to fluoresce, thereby making any defects easily visible. Another frequently used technique is eddy current testing, a non-destructive method that employs electromagnetic induction to identify defects like cracks or delaminations on the surface of aluminum coils. A probe is passed over the coil surface, and any variations in electrical conductivity caused by defects are detected and analyzed. Furthermore, automated systems equipped with high-resolution cameras and image-processing software can also be utilized for surface inspection. These systems capture detailed images of the coil surface, which are then analyzed by the software based on predefined criteria to identify any defects. This method ensures consistent and objective inspection results. Overall, thorough inspection procedures are implemented to detect and address any surface defects in aluminum coils before further processing or usage. These inspections are vital in maintaining product quality, adhering to industry standards, and ensuring customer satisfaction.

- Q:Is aluminium a safe metal to put in ones mouth without any side effects?
- The jury is still out on this one. Aluminum in the body has been directly connected as a causal factor for alzheimer's disease. Think about this : Small amounts of it are infused in many of the things we eat and drink every day. Any food or drink item that comes from an aluminum container has small amounts of aluminum that has leached into those items that you then eat/drink. Aluminum cooking pots/pans are said to leach aluminum into the foods that are prepared in them. Even cooking with aluminum foil adds to the amount of aluminum you are slowly accumulating within your body and brain tissues. The amounts of aluminum we take into our bodies in these ways may be individually small and insignificant as far as health hazards are concerned. But when you add them up over the course of a lifetime the amount becomes rather alarming. As far as aluminum dental tools or prosthetic oral devices braces....who knows how much they contribute to health issues associated with one's overall lifetime exposure. Like I said in the beginning, the jury is still out on this one.
