Grade 11 is very similar to Grade 1, except for the addition of a tiny bit of palladium to enhance corrosion resistance, making it an alloy. Grade 7 is used in chemical processes and production equipment components. In fact, it is most resistant to corrosion in reducing acids. Grade 7 possesses excellent weldability and fabricality, and is the most corrosion resistance of all titanium alloys. Grade 7 is mechanically and physically equivalent to Grade 2, except with the addition of the interstitial element palladium, making it an alloy. It is needed in applications in which high strength is required: Though it is normally used in the following industrial applications, Grade 4 has recently found a niche as a medical grade titanium. It is also known for its excellent corrosion resistance, good formability and weldability. Grade 4 is known as the strongest of the four grades of commercially pure titanium. Grade 3 is used in applications requiring moderate strength and major corrosion resistance. Grade 3 is stronger than Grades 1 and 2, similar in ductility and only slightly less formable - but it possesses higher mechanicals than its predecessors. This grade is least used of the commercially pure titanium grades, but that does not make it any less valuable. This makes Grade 2 titanium bar and sheet are the prime choice for many fields of applications: This grade possesses good weldability, strength, ductility and formability. It shares many of the same qualities as Grade 1 titanium, but it is slightly stronger. Grade 2 titanium is called the “workhorse” of the commercially pure titanium industry, thanks to its varied usability and wide availability. It possesses the greatest formability, excellent corrosion resistance and high impact toughness.īecause of all these qualities, Grade 1 is the material of choice for any application where ease of formability is required and is commonly available as titanium plate and tubing. It is the softest and most ductile of these grades. Grade 1 titanium is the first of four commercially pure titanium grades. Commercially Pure Titanium Grades Grade 1 For specific terminology, please see our ‘definitions’ section at the end of this page. Titanium Grade Overview Titanium Grades and Alloys: Properties and Applicationsįollowing is an overview of the most frequently encountered titanium alloys and pure grades, their properties, benefits, and industry applications.
