Aluminium is the most common metal used for deposition, but other metals such as nickel and chromium are also used. The metal is heated and evaporated under vacuum. This condenses on the cold polymer film, which is unwound near the metal vapour source. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres ...
Copper foil is a thin sheet of copper metal that is widely used in various applications due to its excellent electrical conductivity, malleability, and corrosion resistance. It is an essential material in the electronics industry, especially for manufacturing printed circuit boards (PCBs) and other electronic components.
A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft [dubious – discuss], and a variable-shaped pickup coil. When the coil nears metal, the control box ...
The foil can be used as a pyrotechnic heat source, a replacement of potassium chlorate/iron pellets, for thermal batteries. It reacts faster than the conventional composition, reaches higher temperatures, and heat buffers of inert metal (e.g. steel) are needed to lower the peak temperature and prolong the heat delivery.

Husky 2G is a two-seat variant of Husky MK III vehicle mounted mine detector (VMMD) designed and manufactured by South African firm DCD Protected Mobility (DCD PM). Equipped with a number of sensors , the vehicle is ideally suited for mine-clearing operations including detection, identification and destruction of improvised explosive devices ...
Thor III dismounted CREW system: The Thor III system consists of three dismounted man-pack subsystems, one battery charger, and twenty-four batteries (BB-2590/U). Each subsystem contains a R/T (low band, mid band or high band), a Remote Control Unit (RCU), an integration/pack frame, an Rx/Tx Antenna (low band, mid band, or high band), a GPS ...

[3] [failed verification] In 1836, Michael Faraday observed that the excess charge on a charged conductor resided only on its exterior and had no influence on anything enclosed within it. To demonstrate this, he built a room coated with metal foil and allowed high-voltage discharges from an electrostatic generator to strike the outside of the room.
