Titanium Tubes • Grade 3•UNS R50550

Short Description:

Grade 3 Titanium is a commercially pure (CP) titanium with moderate to high strength, good ductility, and excellent corrosion resistance. It strikes a balance between formability and mechanical performance, making it suitable for pressure systems, aerospace, and chemical processing where strength matters more than GR1/GR2 allow.
