Tantalum

Tantalum (named after the Greek character Tantalus) is a rare, hard, blue-grey refractory metal. It always occurs with the chemically similar Niobium in the mineral ores Tantalite, Columbite and Coltan.

Its main usage is split between two industries 1) it is used as an elemental additive in complex nickel/cobalt based superalloys for jet engines and land based gas turbines 2) it is used in capacitors for the electronics industry and is found in mobile founds, computers, DVD players and computer game systems.

Avon Specialty Metals is competent in the recycling, processing and trading of the following forms of Tantalum: -

  • Spent sputtering targets - pure and alloyed (TaW, TaCrTi, MoTa)
  • Turnings
  • Capacitor pins
  • Anodes (grey and coloured)
  • Scrap sheet, bar, plate, rod, foil from industry
  • EICC approved Tantalum ingots
  • Tantalum ingots remelted from scrap (exempt)
  • Scrap powders
    • ASM is currently in the process of working towards EICC Conflict Free Smelter status, which will further galvanize our strong ethical credentials. We do not source any materials from Central Africa, we do not handle ores/concentrates. Our business model is focussed on recycling high grade scrap of known provenance and primary metal products from EICC approved and/or recycled sources.
