ASTM B394 99.95% Nb1 R04200 Polishing Pure Niobium Tube Pipe
-
- Niobium tube and niobium alloy rods/ bar and wires due to their high melting point, corrosion resistance, good cold working performance, etc, so Widely used in chemical, electronic, aerospace and other fields.Niobium and niobium alloy bars are used as structural materials for aero-engines and rocket nozzles, reactor internal components and wrapping materials for various corrosion resistant parts under nitric acid, hydrochloric acid or sulfuric acid corrosion conditions.
-
- Our Niobium Alloy Tube offers exceptional strength and resistance to corrosion, making it suitable for use in demanding environments.Whether you are in the aerospace, automotive, or energy sector, this tube is engineered to deliver reliable and long-lasting performance. One of the key features of our Niobium Alloy Tube is its lightweight yet robust construction.
-
- This makes it easier to handle and install, while also reducing the overall weight of the structures or systems it is incorporated into. Additionally, the tube’s high-temperature resistance makes it suitable for use in extreme heat conditions, ensuring that it maintains its integrity and functionality under challenging thermal environments.
