Grade 5 is the strongest of all the titanium alloys thanks to its higher aluminum and vanadium content. It offers a versatile mix of good corrosion resistance, weldability, and formability. It's often used for turbine blades, fasteners, and spacer rings.

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.

With a higher iron and oxygen content, Grade 4 titanium is the strongest of the commercially pure titanium alloys, Grades 1 through 4. Although not as strong as Grade 5 titanium, Grade 4 is more corrosion resistant, so it stands up to hydrochloric and sulfuric acids, sodium-hydroxide and ammonia alkalies, and chlorides.

Purer than Grade 5 titanium, these long-lasting rods resist fracturing from use even when cracked.
