Are you interested in tantalum welding? We offer to buy tantalum from the specialized warehouses of the supplier Evek GmbH with delivery to any city. Full compliance with modern quality standards. Supplier Evek GmbH offers to buy rare-earth metals, the price is optimal in this segment of rolled metal products.

General information

Even small quantities of dissolved chemical elements, such as oxygen, nitrogen, hydrogen and carbon, can modify the mechanical properties of tantalum. In addition, the purity of the metal powder, the manufacturing process (sintered or molten quality), the degree of deformation, and the type of heat treatment also affect its mechanical properties. Evek GmbH offers to buy any rare earth metals at manufacturer's price. The supplier guarantees product delivery to any destination.

Technical characteristics

Tantalum has a cubic crystal structure. At -200 ° C, the metal passes from brittle to ductile state. While its tensile strength and hardness increase with cold working, it simultaneously causes the relative elongation of the material to drop. Although the material loses ductility, it does not become brittle. Tantalum's elasticity decreases with increasing temperature, so hot plastic deformation is not used for this metal.

Plasticity

Due to its high level of ductility, tantalum is very suitable for pressure processes such as bending, forming, rolling, pressing or deep drawing. In cold rolling, steel rolls are used and they are lubricated by saponification.

Stamping

The stamping of tantalum bars is done after annealing. When annealed, tantalum is extremely ductile. Only annealed material should be used for deep drawing. The rate of deformation of tantalum billets, as compared to other metals, is reduced by 40...50%. When stamping, it is recommended to use dies made of instrumental alloy steels. The clearance between the workpiece and the tool should be about 6% of the thickness of the processed metal. Low-viscosity technological lubricants are used as a lubricant.

Stamps

The technology of tantalum volumetric stamping is similar to the deformation of low-carbon steels. Stamps made of tool steels are used as tools, and even bronze or copper tools can be used when deformation is small (less than 30...40%).
