CPUA Titanium
Commercially Pure and Unalloyed Titanium Alloys are used in industries where their combined high corrosion resistance and good formability is a necessary requirement, but ultimate strength is not. Commercially Pure Titanium Alloys are those which have a Titanium content of no less than 99%, with additional interstitials containing controlled amounts of Nitrogen, Carbon, Hydrogen, Iron and Oxygen making up the balance. The traditionally termed Commercially Pure grades are Grades 1-4. Grade 1 Titanium has the greatest corrosion resistance and formability with a relatively low strength. The pattern reverses through Grades 2 and 3 until we reach Grade 4 Titanium, which is the strongest Commercially Pure Alloy, but with only moderate formability. Grades 7, 11, 16, and 17 are included in the CPUA category because they only contain trace amounts of Palladium (Max. 0.25%) to increase corrosion resistance. Additionally, Grade 26 is included as it possesses similar mechanical qualities to Grades 7 respectively, but with Ruthenium replacing its Palladium.
