which is the most densiest metal of the world and what is its weight per cubic inch/percubic centimeter?

Depends on temperature. Iridium is most dense at room temperature (22.65 grams per cubic cm) but not at its melting point. See Source

copper, silver, aluminum, lead, magnesium, platinum and tungsten
221298
2.5% copper, 97.5% zinc

I don't remember the ordering, but there's probably some metal out there that won't react?  Gold, maybe?  For regular metal, that sounds a bit iffy.

Tungsten is the strongest metal known to man at this time

3.45×10^−25 kg = Lead-208 atom, the heaviest stable isotope known\n\ncheck here http://en.wikipedia.org/wiki/Orders_of_magnitude_(mass) good luck

Osmium is the densest matter here on planet earth if I recall correctly from chemistry.  Black holes, white dwarves, neutron stars, the big bang singularity... Are all working theories at this point.  Since we can't simulate them in a lab and can't travel to them to sample them, we are stuck with mathematical testing.  So if you want something that you could pick up (you might need a protective suit), then it is osmium.  Otherwise the highest density occurred about 15 billion years ago at the start of the big bang.

I say every single transitional metal is found on every single continent in the world in some quantity.  The most abundant T metal?  I'd say iron.

Such a metal does not exists

A ductile substance is easily pulled or stretched into a thin wire without breaking.\n\n"...gold is the most ductile metal and one gram of it can be drawn into a wire 2,300 meters long."\n\n"The order of ductility of some familiar metals is gold > silver > platinum > iron > copper > palladium > aluminum > zinc > tin > lead"

The heaviest man made element is 112 protons but is unnamed.  #111 is name Roentgenium.

You might be referring to brass, which has a density of 8.5 g/ml.\n\nBronze with 11% tin has a density of 8.1 g/ml.\n\n\nI would guess the brass, since it is more commonly used.

Chrome-moly steel has a density of 7.9g/cc, with an ultimate strength of 520MPa, and a modulus of 200GPa. \n\nTitanium (Ti3Al2.5v) has a density of 4.48g/cc, ultimate strength of 620Mpa, and modulus of 100GPa. \n\nThis means that the titanium is a lot lighter (over 40%), a little stronger (20%), but less stiff (by 50%). A titanium frame will flex a bit more than a steel frame, but that acts as a shock dampener and makes the ride a lot more comfortable. \n\nAluminum (assuming generic) has a density of about 2.8g/cc, ultimate strength of 425MPa, and a modulus of 73GPa. \n\nSo aluminum is actually a lot lighter than titanium, but it is weaker and less stiff (more flexible). \n\nHowever, these numbers are bulk properties, and do not take into account design differences with bike frames. A titanium bike frame will usually be lighter than an aluminum bike frame because you don't have to use as much metal to get the same strength and stiffness with titanium as you would have to do with aluminum and steel. \n\nIt's a LOT more expensive, so unless this is for a racing bicycle, a titanium frame will not be worth the expense.

Aerogel, a silicon dioxide crystal lattice, which is more then 99% empty space is the least dense solid structure.  It also has excellent thermal insulation properties.  It's density is 1mg/cubic cm.  In other words it would take 27738 cubic inches (about half a cubic yard) to weigh just 1 pound.  It is literally lighter then air at standard temperature and pressure.
