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. Performance Tantalum sheets After 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 and Tantalum alloy The 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 and Tantalum alloy Plates are excellent materials for chemical preservation and high-temperature furnaces.
Tantalum sheets Application in the medical field,Tantalum sheets Can be used in artificial ears. For more than 10 years, Hoau has been a leading supplier of rare metals such as tantalum, niobium and its alloys. Relying on China’s abundant non-ferrous metal mine resources, we use exquisite metal processing technology to meet the needs of customers in the fields of chemical industry, optoelectronics, aviation and other fields for non-ferrous metal materials.
