Titanium Alloys
Titanium alloys have more than two dozen variations. Listed below are a few of the more commonly used alloys that account for most applications of the unique metal.
Titanium Grades 1-4 are unalloyed and considered commercially pure. The tensile and yield strength goes up with grade number for these "pure" grades. These grades are used for corrosion resistance and where cost and ease of fabrication and welding are important. These grades are approximately 40% lighter than steel with a high strength-to-weight ratio.
Titanium Grade 5 is the most commonly used alloy of titanium. It is also designated as Ti6Al4V, Ti-6AL-4V or simply Ti 6-4. Grade 5 is often used in aerospace, medical, marine and chemical processing applications. This grade is relatively strong and has better resistance to high temperatures compared to Grade 2.
Titanium Grade 9 - Also known as Ti-3AL-2.5V, this alloy of titanium has higher tensile strength than commercially pure Grade 2 titanium at both room and elevated temperatures. It is also more weldable than Grade 5 titanium.
