Rod Fabrication and Use
X-medics’ tantalum rods are easier machine then traditional wire on spool and been developed to satisfy an increasing demand from our customers. The rods are fabricated from medical grade tantalum metal. The wire is first straightened and then ground several times to ensure very uniform tolerances. The price of rods are higher than material on spool. This is due to the fact that tantalum is ground away during the production
X-medics standard tolerance is +/- 0.020 mm. For selected rod diameters we stock a high tolerance option. On request the higher tolerance can be offered for any size. The high tolerance option is typically used for fabrication of tantalum pin markers.
Surgical unalloyed (pure) tantalum metal is available in two grades – R05200 (electron beam / vacuum arc melted) and R05400 (sintered). Tantalum UNS R05200 and Tantalum UNS R05400 are equally suitable for surgery. The two products have identical requirements concerning the metal content of e.g. niobium, iron, titanium, tungsten, nickel and molybdenum. The mechanical properties are almost similar.

Machining of tantalum by e.g. turning and grinding can be difficult and a proper lubrication is required. X-medics’ tantalum rods are in general easier to handle than wire on spool.
