Available Grades and Materials

We offer various grades to meet your specific requirements:

• Commercial Grade: 99.9% purity for general applications
• High Purity Grade: 99.95% purity for specialized uses

Manufacturing Process

Our seamless tube production begins with high-purity niobium billets. We heat the material to optimal temperatures and use precision extrusion methods. This creates a hollow form without welding or joining. The process eliminates seams that could compromise structural integrity. Each tube undergoes careful dimensional control throughout manufacturing.
