Tantalum is heat resistant and ductile metal with a silvery-gray color. Because of the difficulty in obtaining the metal was named after king Tantalus, known to many by the expression «tantalising». Only the beginning of the twentieth century, the tantalum could be separated from niobium and other impurities and to smelt in its pure form. Its manufacture begins with the receipt of ore concentrate containing approximately 60% of the niobium and 8% of tantalum oxide. Tantalum and niobium separated by extraction and then refining and restore the tantalum. Circle of tantalum, etc. like refractory metals produced by powder metallurgy after the recovery of tantalum metal by the carbon. Processing is performed using a vacuum arc, electron beam or plasma melting. A circle is a semi-cylindrical shape, which is subject to the further pressure treatment.
The wire is usually rolled up to Ø 0,01−3.9 mm.

The beginning of the use of tantalum wire coincided with the beginning of the twentieth century, when there was a search of material for the filaments of light bulbs. Tantalum stayed on the market for a few years and was quickly replaced by more cost-effective tungsten. The massive need for tantalum appeared in the Wake of the development of electric vacuum equipment, Tantalum has a valuable combination of advantages: high emission ability and heat resistance, which give the opportunity to use it in the manufacture of parts radar, radio and x-ray devices. The ability of tantalum to absorb gases helps to maintain the deep vacuum in vacuum tubes. Tantalum wire is used in modern medicine in plastic and bone surgery bone tantalum fasten screws, connect the muscles, ligaments, nerves make prosthetic bones and joints, impose a «patch» in traumatic brain injury. Metal is not irritating to living tissue and does not cause allergies. Tantalum wire demand in cryotron — superconductors used in the calculations.
Certified supply tantalum wire and the circle for the best price. The specification included data on the percentage composition and performance products. We can easily buy in bulk any semi-finished products for large-scale production. We also work with retail buyers. A high level of service, the product compliance with GOST and international quality standards, efficient service are the face of our company. The wire, whose diameter exceeds 1 mm, put in a special technological lubrication. Depending on the diameter, length of wire can be from 150 to 2000 m. the Percentage of impurities in the capacitor wire (with a diameter of 0.01−3.9 mm) corresponds to the content of impurities in the ingot of tantalum.
