Titanium is considered to be one of the strongest metals. Its strength, heat, water and salt resistance, and its light weight make it the ideal metal for a variety of applications. These applications range from jewelry and dental implants to airplanes and ships. Pure titanium is strong and corrosive resistant. Titanium alloys retain the same strength and corrosion resistance, but takes on the greater flexibility and malleability of the metal it is combined with. Titanium alloys, therefore, have more applications than pure titanium. There are six grades of pure titanium (grades 1,2,3,4,7 and 11) and 4 varieties of titanium alloys. Titanium alloys typically contain traces of aluminum, molybdenum, vanadium, niobium, tantalum, zirconium, manganese, iron, chromium, cobalt, nickel, and copper.
The four grades, or varieties of titanium alloys are Ti 6AL-4V, Ti 6AL ELI, Ti 3Al 2.5 and Ti 5Al-2.5Sn.
Ti-6AL-4V is the most commonly used of the titanium alloys. It is therefore commonly referred to as the titanium alloy "workhorse." It is believed to be used in half of the usage of titanium around the world.
Ti 6 AL-4V ELI is commonly referred to surgical titanium because of its use in surgery. It is a more pure version of Grade 5 (Ti 6AL-4V) titanium alloy. It can be easily molded, and cut into small strands, coils, and wires.
Ti 3 AI 2.5 is the titanium alloy with the best weldability. It is also strong at high temperatures like the other titanium alloys. This grade 12 titanium alloy is unique in that it exhibits characteristics of stainless steel (one of the other strong metals), such as being heavier than the other titanium alloys.
Ti 5Al-2.5Sn is a non-heat treatable alloy that can achieve good weldability with stability. It also possesses high temperature stability, high strength, and good corrosion resistance. It has a uniquely high creep (plastic-like strain over long periods of time, usually caused by extreme temperatures) resistance. Ti 5Al-25.Sn is mostly used in aircraft and airframe applications.
Titanium as a whole is a highly durable and strong metal. In its pure form it has many uses. It alloys add greater malleability and flexibility to the already strong metal, opening up doors to many more applications. Each titanium alloy shares the same strength and corrosion resistance. They vary on flexibility, making a specific alloy ideal for specific industries and applications.
