Tantalum plate and tantalum plate applications
Tantalum is a malleable metal that can be processed by cold forging, rolling, punching, drawing, spinning, extrusion, bending, and other methods. The thermal processing of tantalum should be carried out in an inert gas shielded state. PerformanceTantalum sheetsAfter forming an oxide film on the surface of tantalum strip, it can be processed into a round cup six times (without annealing in the process).
Tantalum andTantalum alloyThe plate is a high-temperature, corrosion-resistant material. The chemical stability is similar to that of glass, while the strength and stiffness are comparable to that of mild steel. The high-temperature thermal strength is second only to tungsten and tungsten alloy. With all these properties, tantalum andTantalum alloyPlates are excellent materials for chemical preservation and high-temperature furnaces.
Tantalum sheetsApplication in the medical field,Tantalum sheetsCan be used in artificial ears.
