whats mean shape memory metal?

It's metal that you can set at a specific shape at higher than room temperature.\n\nWhen cooled it can be pulled out of shape but when heated again goes back to how it was set when heated for the first time.\n\nSee http://jchemed.chem.wisc.edu/JCESoft/CCA/CCA2/MAIN/MEMORYM/CD2R1.HTM

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).

Do you see any high performance airplanes  or centrifuge rotors made of plastic instead of titanium?  I think you just answered your question. . .\n\nThat is a little glib, because tensile strength is only one mechnaical property (specific strength, hardness, etc). Stiffness is another reason titantium is popular.  Pure titanium has tensile strengths from 250 to 750 MPa. Ti alloys go up to 1250 MPa. \n\nIf you really only care about tensile strength in **one direction** then there are materials. Heat treatment of carbon fibers can generate tensile strengths as high as 5650 MPa.  Such fibers can be part of a plastic composite and nearly all of them will be less dense than titanium. Molecular weight is ill defined in such compounds and probably not what you meant.

The previous poster is right:  Gold is the most ductile metal.  "Since the cohesive forces are strong and the atoms do not become widely separated from each other during their rearrangement, the metal holds together while its shape is being changed."

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. Substances containing titanium are called titaniferous. \n\nThis element occurs in numerous minerals with the main sources being rutile and ilmenite, which are widely distributed over the Earth. There are two allotropic forms and five naturally occurring isotopes of this element; Ti-46 through Ti-50 with Ti-48 being the most abundant (73.8%). One of titanium's most notable characteristics is that it is as strong as steel but is only 60% its weight. Titanium's properties are chemically and physically similar to zirconium. Notable characteristics Titanium is well known for its excellent corrosion resistance (almost as resistant as platinum), being able to withstand attack by acids, moist chlorine gas, and by common salt solutions. Pure titanium is not soluble in water but is soluble in concentrated acids. A metallic element, it is also well-known for its high strength-to-weight ratio. It is a light, strong metal with low density (60% as dense as steel) that, when pure, is quite ductile (especially in an oxygen-free environment), easy to work, lustrous, and metallic-white in colour. The relatively high melting point of this element makes it useful as a refractory metal. Titanium is as strong as steel, but 43% lighter; it is 60% heavier than aluminium, but twice as strong; however these numbers can vary a little because of the use of different alloys. These properties make titanium very resistant to the usual kinds of metal fatigue. \n\nThis metal forms a passive but protective oxide coating (leading to corrosion-resistance) when exposed to elevated temperatures in air but at room temperatures it resists tarnishing. The metal, which burns when heated in air 610 °C or higher (forming titanium dioxide) is also one of the only elements that burn in pure nitrogen gas (it burns at 800 °C and forms titanium nitride). Titanium is resistant to dilute sulfuric and hydrochloric acid, along with chlorine gas, chloride solutions, and most organic acids. It is paramagnetic (weakly attracted to magnets) and has a very low electrical and thermal conductivity. \n\nExperiments have shown that natural titanium becomes very radioactive after it is bombarded with deuterons, emitting mainly positrons and hard gamma rays. The metal is a dimorphic allotrope with the hexagonal alpha form changing into the cubic beta form very slowly at around 880 °C. When it is red hot the metal combines with oxygen, and when it reaches 550 °C it combines with chlorine. It also reacts with the other halogens and absorbs hydrogen. Applications \nwatches with titanium coverApproximately 95% of titanium is consumed in the form of titanium dioxide (TiO2), an intensely white permanent pigment with good covering power in paints, paper, toothpaste, and plastics. Paints made with titanium dioxide are excellent reflectors of infrared radiation and are therefore used extensively by astronomers and in exterior paints. It is also used in cement, in gemstones, and as a strengthening filler in paper. \n\nBecause of its very high tensile strength (even at high temperatures), light weight, extraordinary corrosion resistance, and ability to withstand extreme temperatures, titanium alloys are principally used in aircraft, armour plating, naval ships, spacecraft and missiles. It is used in steel alloys to reduce grain size and as a deoxidiser but in stainless steel it is employed to reduce carbon content. Titanium is often alloyed with aluminium (to refine grain size), vanadium, copper (to harden), iron, manganese, molybdenum and with other metals. \n\nIts vanadium allo

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.
