It's probably steel, since that offers a good combination of strength, light weight, and low price.  Have you tried a magnet on the metal parts of it?  \n\n If it's not steel, maybe it's stainless steel (which tends to be non-magnetic depending on the alloy) or aluminum, but those are quite a bit more expensive than regular sheet steel.

Bulletproof vests are not made of metal.  They are made of Kevlar which is a polymer.

I've already answered this question and you might want to refer to that for more details. But here goes. \n\nA magnet is made of ferromagnetic materials, and will only attract ferromagnetic materials. These are iron, nickel and cobalt. Any alloy that contains one or more of those is ferromagnetic.\n\nThe metal forms tiny grains as it cools from a liquid to a solid, and within these tiny grains are even smaller regions called magnetic domains. Think of groups of atoms packed together. Unless a material is abolutely pure, there will be odd atoms of other elements and when the metal cools, they do not stack together absolutely correctly. If it is only a tiny amount of impurities, we do not notice the difference in terms of size, shape or weight.\n\nBut the domains are not lined up the same. Think of a bunch of guys just starting basic training. They are all milling around on the parade ground. But let's say that we heat the bar of metal until it is almost ready to melt and then subect it to a strong magnetic field (stick it inside the coil of a strong electromagnet, and let it cool that way.)\n\nNow they are all lined up the same way (just the way a bunch of paper clips will al line up when you pick them up with a magnet.) And when the metal cools and become solid once more, now they stay in that position. It is like a drill sergeant coming and yelling at the new recruits until they line up in formation. Now they are ready to take orders and get some useful work done.\n\nWhen the troops all line up and march the same way, you can see the result. They are more orderly, when they march along their feet all hit the ground at once, and they look unstoppable! \n\nIt is the same way with the magentic material. Each one of the individual atoms has its own magnetic field, but when they are all pointing in random directions, nothing useful can be done. Some are pointing one way, some the opposite way. They act against each other and their corporate effect cannot be felt.\n\nSo, now that the atoms within the domains are lined up together, and the metal has cooled and solidified into a solid bar again, the domains are lined up in formation. Now, they are all pointing in the same direction and we can feel the effects of the magnetic field even outside the magnet itself. The magnetic field reaches beyond the magnet and loops around in space until it reaches the other pole, forming a sort of circuit.\n\nOkay, now we have a magnet and we can understand why it attracts another magnet, because opposite poles attract. north attracts south and south attracts north. (No such thing as gay magnets! it's a law of nature!). \n\nBut why does it attract ordinary non-magnetized iron or steel?\n\nThat has to do with the fact that even though the metal is solid, and the atoms cannot flow away as in a liquid, the atoms are still free to rotate in place without moving from where they are.\n\nThink of the group of raw recruits before they go through their basic training. They are standing around. All of a sudden, they hear a loud noice. It is the drill sergeant yelling at them. All their heads turn in his direction! He has their attention. It is the same way with a magnet.\n\nWhen the magnetic field of a magnet acts on the atoms (iron, nickel or cobalt) of a piece of ferromagnetic alloy that has not yet been magentized, even though the atoms can't move from their spots, they rotate to face in the direction of the magnetic field. They temporarily act together, just as the domains inside the permanent magnet do. The fancy scientific name for this is 'magnetic induction'.\n\nNow, the temporary (induced) pole in the piece of metal is attracted to the permanent pole of the permanent magnet. They move together, because the tendency is for the magnetic field to travel as short a distance as possible, and a pole alwasy induces the opposite pole. The two together, so the magnetic field can travel across the shortest possible distance.\n\nWhen the

Not Steel, but steel alloys.  In particular, stainless steel alloy.

1) German silver  \nGERMAN SILVER [German silver] name for various alloys of copper, zinc, and nickel, sometimes also containing lead and tin. They were originally named for their silver-white color, but use of the term silver is now prohibited for alloys not containing that metal. German silver varies in composition, the percentage of the three elements ranging approximately as follows: copper, from 50% to 61.6%; zinc, from 19% to 17.2%; nickel, from 30% to 21.1%. The proportions are always specified in commercial alloys. German silver is extensively used because of its hardness, toughness, and resistance to corrosion for articles such as tableware (commonly silver plated), marine fittings, and plumbing fixtures. Because of its high electrical resistance it is used also in heating coils. It was discovered (early 19th cent.) by a German industrial chemist, E. A. Geitner. \n\n2) galvanizing  \nGALVANIZING [galvanizing] process of coating a metal, usually iron or steel, with a protective covering of zinc. Galvanized iron is prepared either by dipping iron, from which rust has been removed by the action of sulfuric acid, into molten zinc so that a thin layer of the zinc remains on the surface of the iron upon removal or by a method of electroplating. Iron is also coated with zinc by a method in which the iron is first covered with the zinc dust and then baked; an alloy is formed at the surface, the resulting product being known as sherardized iron. Sheets of pure iron, copper iron, and various steels, as well as wire and netting, are often galvanized, since the zinc coating resists oxidation and the action of moisture very successfully. When the coating is broken or pierced some protection is still afforded, since the zinc reacts with the corroding agent first.

As a former US Army officer and having recently returned from working with the troops in Iraq for 18 months I can assure you that every single commissioned officer (and NCO & enlisted member) wears a set of Dog-Tags.\nFor each service they are a little different regarding the information stamped on them.  \n\nUS ARMY tags contain - example\nWilson                     (surname)\nRichard A                (first name, middle initial)\n222-444-5678        (social security number)\nA POS                     (blood type)\nLDS/Mormon          (religious preference)\n\nUS NAVY tags contain - example\nBenson\nRichard J\n23 NOV 1950           (date of birth)\nCommander              (rank)\n18 May 1992             (tetanus shot date)\nAB -                            (blood type)\nCatholic                      (religion)\n\nUS Air Force tags-contains at least, perhaps more\nCampbell\nDavid F\n234-456-1234            (SSN)\nO                                 (blood type)\nLutheran                      (religion)\n\nUS Marine Corp tags contain - example\nTemple\nSteven S\n557-999-0770     B +   (SSN)  (blood type)\nUSMC                  M      (service) (Gas Mask size)\nNone                             (religious preference)\n\nAll military members wear a set of 2 tags.  In the event of death while on duty (killed in action, etc), one tag stays with the soldier, sailor, marine or airman as identification.  The 2nd tag is normally secured by the officer or NCO in charge or on the scene for various administative reasons.  To my knowledge the only service members who do not wear their dog-tags are the special operations people (SF, SEALs, Delta, Rangers) who are out on classified operations.\n\nI hope this information is sufficient to answer your question.

Both.  Electrum, a naturally occuring alloy of silver and gold, is the only one I can think of, but I'm sure there are more.  However nearly all alloys used today are articial (think of steel).

I'm not sure they use metal strips, but if they do they will be spring steel.. Spring steel is everywhere. \nI think they are more likely to use composite materials such as graphite, kevlar or glass fibre. Again these are really readily available.\nAll these materials are not really off the shelf items and are made for specific uses. You will find composite manufacturers in your yellow pages or on the internet. Hopefully they would have some local to you.

Anything containing Iron or Steel.  Any Ferris material.  Steel is made from iron, however, stainless steel is not magnetic.  Aluminum, copper, brass, gold, and silver are not magnetic.

Of the ones you listed Aluminum would be the best mostly because it is a metal.
