Titanium Round Bars

Titanium is classified into different grades based on its composition and mechanical properties. The "round" aspect you mentioned likely refers to round titanium bars, rods, or wires available in these grades. Here’s a breakdown of common titanium grades:

Commercially Pure (CP) Titanium Grades (Grades 1–4)

These grades contain only trace amounts of alloying elements, making them highly corrosion-resistant and formable.
  • Grade 1 – Softest and most ductile, excellent corrosion resistance, used in chemical processing and marine applications.
  • Grade 2 – The most commonly used CP titanium, offers a good balance of strength, ductility, and corrosion resistance.
  • Grade 3 – Stronger than Grades 1 and 2, but slightly less formable; used in aerospace and industrial applications.
  • Grade 4 – Highest strength among CP titanium grades, ideal for medical implants and industrial applications.

Titanium Alloys (Grades 5 and Beyond)

These contain additional elements like aluminum and vanadium for enhanced strength and performance.
  • Grade 5 (Ti-6Al-4V) – The most widely used titanium alloy, combining high strength, corrosion resistance, and good weldability; used in aerospace, medical, and automotive industries.
  • Grade 6 (Ti-5Al-2.5Sn) – Used in high-temperature environments, such as jet engines and aerospace applications.
  • Grade 7 (Ti-0.2Pd) – Similar to Grade 2 but with added palladium for superior corrosion resistance, used in chemical processing.
  • Grade 9 (Ti-3Al-2.5V) – Lower strength than Grade 5 but more formable, commonly used for bicycle frames and sports equipment.
  • Grade 23 (Ti-6Al-4V ELI) – Extra-low interstitial version of Grade 5, providing improved toughness and biocompatibility for medical implants.

Titanium rounds (bars, rods, wires) are available in these grades for various applications, from aerospace to medical devices. The choice depends on factors like required strength, corrosion resistance, and machinability.
