Where other metals exhibit limited lifespan, titanium endures. The specific gravity of titanium is 4.51 g /cm3 - about 60% that of steel, half that of copper and 1.7 times that of aluminum. In addition to having excellent mechanical strength (comparable to mild steel), titanium is durable and shock resistant.
Russia is located on both the European and Asian continents. The continental divide is the Ural Mountains, Asia on the east and Europe on the west. Russia is partly in Europe â¦ and partly in Asia. Or to clarify (slightly) the above: Russia is in Europe while Siberia and many other states in the Russian Federation are in Asia. Basically, west of the Urals is in Europe.
The seven-continent model is usually taught in China, India, Pakistan, the Philippines, parts of Western Europe and most English-speaking countries, including Australia and the United Kingdom.

The six-continent combined-America model is used in France and its former colonies, Italy, Portugal, Spain, Romania, Latin America, and Greece.
