Pure tantalum has good plasticity, low deformation resistance, and low work hardening rate. Various profiles and special-shaped parts can be made by plastic processing methods. Pure tantalum can be rolled into sheets, strips, foils, pipes and bars at room temperature, and the processing rate can reach more than 90%. To reduce oxidation, pure tantalum plastic working is often carried out at room temperature or below 500 °C. Due to the high strength and poor plasticity of the ingot, the tantalum alloy must be billeted above 1200 °C, and the subsequent processing technology is the same as that of pure tantalum. The extrusion ratio of the billet should be greater than 4, and the forging ratio should be greater than 2. When the ingot is heated and opened, it is necessary to prevent gas pollution and reduce the plasticity of the material. In order to ensure that the product has good stamping and spinning properties, cross rolling is used. The processing rate before cross rolling should be kept around 80%. The tantalum plate can be made into cups, caps, tubes, cones, nozzles and other parts of different shapes by spinning and deep drawing. The diameter of the swaging rod for wire drawing is generally 2.5 mm. Because tantalum is soft and easy to bond with the mold and scratch the surface, the wire surface is often anodized to form an oxide film, and lubricated with beeswax.
