Tantalum rods have strong corrosion resistance to most acids, alkalis and salts at room temperature. Tantalum bars form an oxide film in the air. This oxide film makes the Ta rods resistant to oxidation.At high temperatures, tantalum bars do not react to most chemicals.Tantalum rods are an ultra-high temperature metal.
Tantalum rods have a very high melting point. Tantalum rod has good ductility and plasticity. At high temperatures, tantalum rods can be stretched and rolled into tantalum foils and tantalum wires. Tantalum rods have very good electrical and thermal conductivity.

Pure tantalum rods can be used to manufacture jewelry, such as tantalum rings. Tantalum rods can also be processed into industrial tantalum valves. Tantalum valves can be used in high temperature environments. Tantalum bars can also be made into tantalum electrodes to extend the service life of the electrodes. Tantalum rods can also be used to process tantalum parts into electronic devices such as mobile phones, computers, and automobiles. In the semiconductor industry, Ta rods can be processed into tantalum processing workpieces with stable performance. Tantalum rods can be processed into bone fixation devices and joint replacements for medical purposes. Because tantalum implantation can be long-term contact with human tissue without causing rejection. Ta bars can also be used to make medical devices. Tantalum rods can be processed into high-temperature components for aerospace applications such as rocket engines and jet engine components.
In addition to Tantalum Rod&Bar, we also produce Tantalum Sheet & Plate, Tantalum Ingot, Tantalum Pellets, Tantalum Foil, Tantalum Wire, Tantalum Disc, Tantalum Shield, Tantalum Target, Tantalum machined parts, Tantalum Spherical Powder. They meet Standard ASTM B 364, ASTM B 365, ASTM B 708, ASTM B 521, ASTM F560 R05200, R05400.
