What is the most common metal/alloy material found in asteroids?

Go here, it has an easy to read chart on composition. Most asteroids are carbon based. Asteroids with iron in them usually also have lots of silica.\n\nhttp://jade.ccccd.edu/jwilson/asteroids.html

Planets and asteroids.\n\nAll the planets in the solar system have a natural satellite except Mercury and Venus. \n\nSeveral asteroids are doubles, which two similarly sized components - so they don't count. But there are cases of asteroids with much smaller companions. So you can call these asteroids with moons.\n\nComplete lists of double asteroids - which includes asteroids with little companions (asteroid moons) is here:\nhttp://hea.iki.rssi.ru/~denis/doublemp.html\nhttp://www.johnstonsarchive.net/astro/asteroidmoons.html

Chromite is iron magnesium chromium oxide: (Fe,Mg)Cr2O4\n\nIron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), limonite or siderite.

The answer is: it is pretty hard to find them.\n\nThe easiest ones to find are iron meteorites, litterally hunks of iron from space.  The tend to have a black crust, but will look like mangled chunks of iron.\n\nFor your more stone-like meteorites it gets harder.  A metal detector still helps, as even most "rock-like" meteorites still have lots of iron and nickle in them.  Generally they will appear as dark black rocks, due to the surface of the rock having been melted during entry into the atmosphere.  Finding them in the mountains will be _very_ tough, as they really, really just look like most of the rocks sitting around.\n\nThe desert is a bit easier, especially if it is a more or less sandy desert.  If you are someplace without any rocks (like a sand dune desert) and you come across a dark, black rock, you may have found one.  The easiest way to find them it to go to places like this, where a dark black rock will stand out against the background.  Most proffesional meteorite collection efforts take place in places like the sahara desert, and antarctica.\n\nTo really identify them outside of these "easy" circumstances you will really need to train yourself up.  There are field guides out there that can help train you to look for the slight tell-tale signs that the rock you are holding is not from our planet.

Rutherfordium, Rhenium, Rhodium, Ruthenium...ahh Rubies...take your pick.

I have disagree with the first answer as 35% of the earth is Iron. And while Aluminum is more abundent on the surface, nearly 80% of the core is iron. So I have to go with Iron.

I believe it is iron.  Not an expert though.

the most abundant substance in the earths crust is silicon dioxide (sand) and the most abundant on the planet is iron (the core is essentially all iron)

Iron. \n\nThat 46% figure for oxygen is not correct because it is only for the earth's crust. It does not include the mantle or the core. \n\nFor the entire planet iron makes up 35% of the mass of the planet and oxygen is only 30%. Silicon is 15%, magnesium 13%, and everything else is 7%. \n\nMy source is the USGS (which also cites the 46% oxygen for crust):\nhttp://pasadena.wr.usgs.gov/office/ganderson/es10/lectures/lecture04/lecture04.html

Tell me wat kinda??\nModel rockects wooden body, or thin sheet of metal, depends on the strength required...\n\nHuge rockets, alloy named duralium and magnalium, And other alloys containin aluminium and tungsten because aluminium is very light and tungten gives it strength and stablity at high temperatures\n\nU even use carbo-fiber polymere's modified to sustain heat.

While Glass is technically not a metal being composed of silica compounds of various types, the quickest cooling true metal is mercury...yes mercury is a metal...titanium is next followed by bauxite the main ingredient in aluminum.

Aluminum. Lightweight, Durable. Its a metal so its way more reflective (good for sattelites) and it would stand up to weather better.

alloy is made of steel and iron....and maybe iron or aluminium can be mixed with lead =)

Most asteroids are made of rock and metal, not ice.  Comets, on the other hand usually do contain “dirty ice.”\nIndeed comets are being “freeze dried” in space, but it is when they approach the sun that the ice begins to melt forming the coma and tail of the comet.\nThe reason that comets do not completely “freeze dry” in space is due to their size.  Freeze drying only occurs on the outside of the comet, not on the inside.\nSee the site below for more details:
