o njews'istai cia jau virs interneto? :)) .. zodziu, as irgi ta pati..
gugliawike pasinaudojau.. bet rysium su tuo, kad as antistrongines
fizikos zinias turiu, tai ir nezinau, ar mano nuojauta citatoms pasiteisins.

na vertalas is wiki ko gero:
Titanium ***alone*** is a strong, light metal. It is stronger than common, ***low-carbon_steels***, but 45% lighter.
It is also twice as strong as *weak* aluminium ***alloys*** but only 60% heavier.

Grade 5, also known as Ti6Al4V, Ti-6Al-4V or Ti 6-4, is the most commonly used alloy.
It has a chemical composition of 6% aluminium, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder 
titanium.[5]

Since it is the most commonly used alloy – over 70% of all alloy grades melted are a sub-grade of Ti6Al4V,
its uses span many aerospace airframe and ****engine_component**** uses and also major non-aerospace
applications in the marine, offshore and power generation industries in particular."[7]

"Applications: Blades, ****discs****, rings, airframes, fasteners, components. Vessels, cases, hubs, forgings. Biomedical 
implants."[5]

Generally, Ti-6Al-4V is used in applications up to 400 degrees Celsius. It has a density of
roughly 4420 kg/m3, Young's modulus of 115 GPa, and tensile strength of 1000 MPa.[8]
By comparison, annealed type 316 stainless steel has a density of 8000 kg/m3, modulus of 193 GPa, and tensile strength of only 570 
MPa.[9]
And tempered 6061 aluminium alloy has 2700 kg/m3, 69 GPa, and 310 MPa, respectively.[10]
