| Product | Tantalum Niobium Tube (Ta-Nb Tube/Pipe) |
| Part Number | TRM-TA005 |
| Standard | ASTM B521 UNS R05240 |
| Type | Seamless or Welded |
| Assay | Tantalum- 40% Niobium |
Tantalum niobium tube (Ta-Nb alloy) typically refers to 40% of the Niobium content. However, we can also offer the tantalum niobium alloys with different niobium contents, such as 3% Niobium, 20% Niobium, 30% Niobium, and etc. This alloy has the good high-temperature mechanical properties. Please contact us for more details.
Application: The Tantalum Niobium Tube is used in the production of the electronic components, and etc.
