When a chemical element is mixed with titanium sheet it is known as a titanium alloy. Titanium, in pure form, is a white, very reactive metal. This is why it is commonly combined with other materials to form an alloy. For reference, titanium is 60 percent heavier than aluminum but lighter than steel by 40 percent. Titanium has an extremely low density and is extremely strong which makes it perfect to be combined with other metals for a variety of uses.
Because these metallic mixtures are known for being extremely tough under extreme temperatures, lightweight and resistant to corrosion, they are commonly used in a variety of materials include those used for space exploration and military applications. They are even used in high-end sports cars and consumer electronics. Such alloys are especially common in medical and dental implants. Other uses for titanium include jewelry and a wide variety of spacecraft and missiles.
Titanium is commonly mixed with vanadium, molybdenum, aluminum and iron, among others. There are many types of titanium alloys and various grades of mixtures. The most common, however is known as Grade 5 Titanium Alloy, also known as Titanium 6AL-4V. This mixture is 90 percent titanium, 6 percent aluminum with the remainder being vanadium. This grade can handle up to 400 degrees Celsius (752 degrees Fahrenheit). It is commonly used in aircraft.
Did you know that almost 65 percent of all titanium manufactured is used in aircraft and marine equipment? It is even used in white paint and even sky writing! Titanium tetrachloride makes thick clouds which can be used to write though the sky, even in moist air. You find titanium all around you. Whether you wear glasses, have a metal replacement in your body or fly around in an airplane occasionally, you have encountered this metal.
