A favorite with chemical processing applications that require anti-corrosion characteristics is tantalum rod including the manufacturer of components for anticorrosion equipment.

Outstanding refractory, anti-corrosion and biocompatibility properties make our tantalum wire a unique material for selected applications. Customers transform our tantalum wire into leads for Ta capacitors in electronic, anti-corrosion chemical processing, biomedical devices for medical applications, and filaments for lighting applications.

H.C. Starck’s tantalum rod is worked cold from ingot to final diameter. Forging, rolling, swaging, and drawing are used singularly or in combination to reach the desired size.

Proprietary techniques have been developed by H.C. Starck to overcome the metal's extremely high-galling tendencies. Special lubricants and die design, as well as suitable speeds and reductions per pass, are all a part of cold drawing tantalum.

Our tantalum rod is generally supplied with a forged surface above 1-3/8" diameter and a swaged or drawn finish in smaller diameters. The rod, preferably unannealed, may be centerless ground to improve diameter tolerances. The minimum diameter for centerless grinding is .125".

H.C. Starck’s tantalum rod is produced to a maximum of 1/4" and wire may be supplied in coils or straightened and cut to length.

Tantalum wire with a diameter of 0.040“or below is shipped on spools.

ULTRA76 tantalum alloys offer higher corrosion resistance in most environments creating additional value through extending the products service life, reducing material thickness and improving processes throughput.

  • Higher temperatures possible, shorter cooling/heating cycle times
  • Constant surface finish (Ra<0.8 micrometers)
  • Tantalum material only from non-conflict sources - EICC certified
  • Uniform wall thickness
