Tantalum bars are solid, rectangular-shaped pieces of tantalum metal. They are typically available in various dimensions, lengths, and purity levels, depending on the specific application. Tantalum bars are often used in the production of high-temperature parts, such as heating elements, vacuum furnace components, and sputtering targets for thin film deposition. They can also be employed in the manufacture of corrosion-resistant equipment, such as heat exchangers and chemical reactors.

Tantalum wires are thin, elongated strands of tantalum metal. They are commonly available in different diameters and lengths, depending on the intended use. Tantalum wires possess excellent electrical conductivity and resistance to oxidation, making them suitable for applications where high-temperature and corrosion resistance are required. They are commonly used in the electronics industry for capacitor components, as well as in the production of filaments for high-intensity lighting and electron beam welding.
