Rod Fabrication and Use
X-medics’ tantalum rods are easier to machine than traditional wire on-spool, and have 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 precisely uniform tolerances. The price of rods are higher than material on-spool due to the precision work of grinding and smoothing the tantalum during the production process.
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.

The precision work of machining tantalum by 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.
