Most metal detectors use ordinary alkaline batteries, but newer ones may use other types of batteries. Check the owner's manual for the specific model of metal detector to determine the correct battery for it.
Because it a good metal
aluminium is used for making electrical cables as the metal do not melt easily
the metal detcetor always used mainly for detect or find the metal weapons, metals wires, chemical jars/ metal box containing harmful drugs and explosives. it is helped out for alarming illegal import/export gold,silver metals.

consruction metal domes
Many different metals are used. Jewelry is often based on certain expensive metals such as gold, platinum, or silver, but other metals are used as well.
He used a Minelab Explorer SE Pro Metal Detector with a standard head.
Germanium is a metalloid. It exhibits properties of both metals and non-metals, making it a semiconductor commonly used in electronic devices.
What white metal is used for largely depends on what type of white metal one is discussing. White gold and platinum tend to be used in jewelry making and are very expensive. Other white metals such as chromium may be used in the making of coins.
Well , to be honest i belive in 1867 ....
Click on the link below for the answer. Common metal detectors work by sending out a radiofrequency energy signal. This frequency will change slightly when the 'antenna' is in close proximity of various metals. Many metals will absorb this energy. The detector notices this absorption and can these days indicate what metal it is and even the distance to the metal. Some metals also reflect this energy signal and when a reflection is picked up, this can also be used to indicate type and size of metal object. High tech detectors use a combination of many methods of which increases its accuracy drastically.
The operation of metal detectors is based upon the principles of electromagnetic induction. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground. The single-coil detector illustrated below is a simplified version of one used in a real metal detector. Muhammad Abubkr Saeed
