Because Grade 2 titanium is 99% pure, it is more corrosion resistant than Grades 5 and 9 but not as strong. It has good formability and weldability. Common uses include chemical-processing equipment, heat exchangers, and marine hardware.

Bend this wire and it will stay in place. Because Grade 2 titanium is 99% pure, it is more corrosion resistant than Grades 5 and 9 but not as strong. It has good formability and weldability. Common uses include chemical-processing equipment, heat exchangers, and marine hardware.

These titanium rods are the strongest of the commercially pure titanium alloys, Grades 1 through 4, and resist corrosion better than Grade 5 titanium. However, they’re not as strong as Grade 5, and they won’t bend or form as easily as lower grades. Use them in chemical processing and marine environments. Nearly 99% pure, these rods won’t corrode from chlorides or oxidizing acids, such as hydrochloric and sulfuric acids. They also stand up to alkalis, such as hydroxide and ammonia. With more iron and oxygen than lower grade titanium, these rods are lightweight as well as strong. They also withstand impacts at low temperatures.

Grade 9 titanium has less aluminum and vanadium than Grade 5, so it's easier to weld but not as strong.

Purer than Grade 5 titanium, these long-lasting rods resist fracturing from use even when cracked. They’re also easier to form into shapes than Grade 5 titanium and lighter in weight than steel. Thanks to their aluminum and vanadium content, these rods are stronger than pure titanium, though they’re not as strong as Grade 5. They won’t rust, even in marine or saltwater environments. All meet ASTM F136 and ISO standards for biomedical use. They also meet ASTM B348 standards for titanium alloys. Grade 23 titanium is also known as 6-4 ELI and Ti-6Al-4V ELI titanium.
