Why is titanium so strong??

It is just from the way that the elements are fused together to form the compound. It's the same as any other metal.

Titanium is a chemical element in the periodic table that has the symbol Ti and atomic number 22. It is a light, strong, lustrous, corrosion-resistant (including resistance to sea water and chlorine) transition metal with a white-silvery-metallic colour. Titanium is used in strong light-weight alloys (most notably with iron and aluminium) and its most common compound, titanium dioxide, is used in white pigments. now only inner transition elements are radioactive, and transition elements are non radioactive, hence my friend titanium is not radioactive . take care

However, writer Douglas Adams observed that, "...because flight recorders are made out titanium\n\nhttp://en.wikipedia.org/wiki/Black_Box_%28transportation%29

Hardness.  Bones are made mostly of calcium (which does have the properties of a metal in it's elemental form).  When your born, you don't have very many bones - it's mostly cartlidge, like the stuff that makes up the tip of your nose and the top part of your ear.  This is a very flexible substance (and that's good cause babies need to be flexible to get out of their moms).  As you get older this cartlidge is replaced with a calcium matrix and your bones get harder.\n\nThe mineral deposites in your bones are the reason why you break your leg when you fall out of a tree instead of just bending it a little.

Typically when a material is refered to as strong, you are refering to its mechanical property can 'Tensile Strength' - How much force you can pull it with before it breaks.\n\nIt terms of what makes one material strong compared to another, is related to many factors - On a microscopic level, basically how easy it is for discontinuities in the material to move.\n\nWith reference to your concrete example, the reason concrete of a skyscraper is strong, primary is because it is steel reinforced; steel bars are embeded inside the concrete - The combination of steel and concrete is a good one because steel is very strong in tension (which concrete is not) but concrete is very good in compression.\n\nWhen you combine different materials like this, the resulting material is refered to as a composite. Composites presently are the best structural materials that we have; examples are fiberglass/polyester and  carbon/epoxy. Carbon/epoxy is extremely popular for aerospace structures because of its high strength and low weight, as well as its durability. When composites first appeared, they were very expensive and limited to really hi-tech applications like aerospace, but today you can find them everywhere - golf club shafts are commonly carbon/epoxy for example.

I plan on keeping mine in for the rest of my life with no rusting.  I would think that in a few million years if they find even my bones decayed away, that titanium will still be sittin' there shining nice and pretty.

titanium is quite rare and expensive.\n\nuse wikipedia.org and links in it to get more info\n\nPeople will not think that you're stupid, they'll think that you're lazy :)

Metal detectors either sense distortions in magnetic fields, or nuclear density- Titanium is one of the most non-magnetic metals, and is quite light (low nuclear density).

The melting point of titanium is approx. 1660 Celcius

Different metals have different magnetic field strengths.\n\nFor example, neodymium magnets are among the strongest.

Silver has a higher reflective index than any other industry-related metal anhydride.  For economic purposes, titanium isn't used in most commercial labs.  However in some superconductors, the 0.003% difference is crucial.  Though it costs much more.

Yes, Titanium is a non-ferris (not magnetic) metal and will not harm you when/ if you have an MRI, though the screws look cool on the film

Because it is an element.\n\nVanadium is probably one of those obscure metals that you don't learn much about in school. Basically, it is an element found as a part of several minerals. Now it's used in nuclear power plants and purification processes. You'll find it in the top row of transition metals just to the right of titanium. \n\nIt was discovered and named in 1901 by a scientist named del Rio in Mexico and later by another scientist named Sefstrom in Sweden. It was named after the Scandinavian goddess Vanadis. It wasn't until 1867 that pure vanadium was isolated. When purified, vanadium is a bright white metal. \n\nva·na·di·um  (v-nd-m)\nn. Symbol V\nA bright white, soft, ductile metallic element found in several minerals, notably vanadinite and carnotite, having good structural strength and used in rust-resistant high-speed tools, as a carbon stabilizer in some steels, as a titanium-steel bonding agent, and as a catalyst. Atomic number 23; atomic weight 50.942; melting point 1,890°C; boiling point 3,000°C; specific gravity 6.11; valence 2, 3, 4, 5. See Table at element.

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.

Titanium is extracted from ilmenite (FeTiO3) and rutile (TiO2). Brazil, India, and Canada are major producers. Both these ore minerals are found either in rock formations or concentrated in heavy mineral sands.

It can only hold the weight of 16 pennies.  He-He.  Just kidding.  Actually, that's a good question.  I've been a carpenter all my life and to tell you the truth, a 16d nail is one damn strong piece of metal.  Ever pull one out of a piece of lumber that was shot in with an air gun?  It'll make you grunt, that's for sure!  One that's galvanized is even more difficult.  And if it's a ring-shanked nail?  Forget it.  It's in the lumber until the wood rots.  It's really not a matter of how many pounds it can hold.  It's a matter of its bonding power.  You can bend a 16d nail quite easily, but after it penetrates into a 2 x 4, for example, it's meant to stay, depending on how it was put to use "structurally".
