The Properties of Titanium and Its Alloys

Titan je metal srebrnosive boje i visokog sjaja, deveti je element po obilnosti u Zemljinoj kori, a moguæe ga je naći i u meteoritima. Ima nisku električnu vodljivost i mali koeficijent toplinskog širenja. Kako titan ima veliku pasivnost, njegovo fizikalno svojstvo je visoka razina korozijske otpornosti na većinu kiselina i mineralnih klorida. Mehaničkih je svojstava poput čelika, ima visoku temperaturu taljenja i lagan je. Budući da je vrlo otporan na koroziju primjenjuje se u proizvodnji osovina propelera i drugih brodskih dijelova koji su izloženi morskoj vodi. Netoksičan je, nemagnetičan i antialergen, biološki kompatibilan s ljudskim tkivom i kostima što ga čini idealnom materijalom za medicinske proizvode implantata. Titan s metalima aluminijem, kromom, željezom, molibdenom, kositrom, vanadijem, cinkom i drugim tvori legure različitih fizikalnih, kemijskih, strukturnih i specifičnih svojstava, različitih tvrdoća, čvrstoća, žilavosti, otpornim na koroziju, oksidaciju i ostale potrebite uvjete.Titanium metal is silver-grey color and high gloss, the ninth element of the abundance in the Earth’s crust, and can be found in meteorites. It has a low electrical conductivity and low coefficient of thermal expansion. Since titanium has a great passivity, its physical property is a high level of corrosion resistance to most mineral acids and chlorides. It has mechanical properties such as steel, has a high melting temperature and is light. Since it is highly resistant to corrosion it is applied in the manufacture of propeller shafts and other ship parts that are exposed to seawater. It is non-toxic, nonmagnetic and antiallergenic, biologically compatible with human tissue and bone, which makes it an ideal material for medical implant products. Titanium, together with metals aluminium, chromium, iron, molybdenum, tin, vanadium, zinc and other, forms various alloys of physical, chemical, structural and specific properties of different hardness, strength, toughness, corrosion-resistance, oxidation and other necessary requirements
