Tantalum

Tantalum (Ta) is a dark blue-gray metal that is very heavy, ductile and hard and has high corrosion resistance. Tantalum is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluouric acid. It has the fourth highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors, making it an excellent material for tubes.RIMCO OVERSEAS is a trusted SUPPLIER of tantalum tube and a wide variety of tantalum products. Other shapes are also available upon request including tantalum capillary, tantalum sheet / tantalum board, tantalum wire, tantalum foil / tantalum strip, etc.
Tantalum tube can be applied in fluid material tanks along with other glass-lined containers, tantalum thermo few and tantalum thermocouple safeguard sheaths, tantalum thermo well, tantalum emitter, tantalum sleeve, tantalum plasma spray focus on and tantalum tubular sputtering target. Products:
Wire , Spring hard wire , Fller wire , Block , rod , Round bar , Square , Hex , Strips , Flat ,Foil , Sheet , Coil , Slitting coil , Plate , Tubes , Pipe , Seamless Pipes , Capillary Tubes , Fittings , Flanges , Fastner , Nut Bolt , Wire mesh , Crucibal , Beekar , Scrap , Ingot , Ring , Bushes , Disc , Rectangles.

Tantalum tube is largely applied to produce tantalum response vessel, tantalum heat exchangers(shell & tube heat exchanger), tantalum pipe line(piping or channel), tantalum condenser, tantalum agitator, tantalum cooler, tantalum boiler, tantalum bayonet heater, tantalum spiral (helical) coil, U-tube heat exchanger or "U" tube bundle heat exchanger during the substance sector for condensing, re-boiling, preheating and cooling of nitric acid, sulfuric acid, hydrochloric acid, formic acid and combinations of those acids with a great deal of other chemicals.

ASTM B365

RIMCO OVERSEAS supplies sheets and plate products in a wide range of thicknesses and widths. We can offer flat rolled material cut to specific lengths or we can supply coiled sheet or strip shipped 0n cores. Although our products are typically produced to meet ASTM specifications, other specifications are available upon request.
RIMCO OVERSEAS offers both powder metallurgy and typical electron beam processed tantalum sheet. The powder metallurgy grade tantalum is perfect for deep drawing and stamping applications.Its provides a fine grain structure and is isotropic. Therefore parts are less likely to be pitted or have rough surfaces. For high temperature applications such as furnace parts . This product is engineered to significantly increase the product life by slowing grain growth at high temperature.

Tantalum Bolt & Fastener can provide custom tantalum fastener solutions for your unique tantalum bolt, tantalum nut & tantalum screw applications. Just let us know the requirements of your tantalum fasteners and our engineering staff will help guide you to the best solution for your tantalum fastener application.
RIMCO OVERSEAS tantalum fasteners are optimized concerning chemical and mechical performance.RIMCO OVERSEAS's fasteners offer the full corrosion resitance of Tantalum, but are mechanically improved due to their steel core and Tantaline's patented Alloys bonding technology. RIMCO OVERSEAS's tantalum fasteners offer a corrosion performance that is well beyond that of titanium or other Speciality metals like zirconium or HastAlloys.
Tantalum fasteners are also extremely stable at high temperatures, since its melting point around 3000C. Furthermore, tantalum fasteners are also one of the most bio-compatible metals around and because of is high density (16.68 g/cm3) its radio-opaque. All tantalum fasteners are available in commercially pure tantalum, tantalum 2.5% tungsten (Ta-2.5%W) and tantalum 10% tungsten (Ta-10%W).
