Tantalum is dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity and is featured the third highest melting point 2996℃ and high boiling point 5425℃. It has the characteristics of high temperature resistance, high corrosion resistance, cold machining and good welding performance. Therefore, tantalum and its alloy are widely used in electronics, semiconductor, chemical, engineering, aviation, aerospace, medical, military industry etc. The application of tantalum will be more and more widely used in more industry with the technology progress and innovation. It can be found in cell phones, laptops, game systems, automotive electronics, light bulbs, satellite components and MRI machines.


The tantalum plate, sheet, strip and foil surface should be smooth, clean, greaseless, without fissure or burr, no mess around, no knotting, no crossover, no continuous pitches or scratches. Most foils are produced from cast ingots which are used in coating and thin film.


Towin Rare Metals produce RO5200, RO5400 with different dimensions of the tantalum plates, tantalum sheets and tantalum foils. Moreover, we guarantee the tantalum purity is between 99.9% to 99.95% or higher. We also make sure of excellent properties performance. The size can be tailored by the customers’ requirements. We control our products quality through the raw material source till the whole production line and finally deliver to our customers in order to make sure you purchase our products with stable and same quality each lot.
