SCC 104 coltan

Coltan in "Heavy Metal".


Coltan is the colloquial African name for columbite-tantalite, a metallic ore used to produce the elements niobium and tantalum. The endoskeletons of advanced Terminator machines are made using alloys derived from a half percentage of coltan to make them hardened to heat. [1]

T-600s were made of a titanium alloy endoskeleton design, but were vulnerable to heat. Coltan alloys have a much higher melting point, making it a superior alloy for endoskeletons.

When John Connor asks, hypothetically, how many Terminators could be built from the shipment of Coltan the trio witnessed in "Heavy Metal", Cameron replies with: "530 endoskeletons."

Cameron sends the shipment dramatically off the edge of a steep cliff into deep waters, preventing those 530 endoskeletons from being manufactured post-Judgment day. She does, however, retain one Coltan rod, perhaps for future repairs of her own endoskeleton.

Zeira Corporation owns 7% of the Earth's Coltan reserves.


John: That's coltan; if that's what you're made of, no wonder you're so dense.
Cameron: Not density, heat resistance. T-600 models had a titanium alloy endoskeleton, but it was vulnerable to heat. Coltan alloys have a much higher melting point.

  • Coltan has recently incited a war in Africa [2]
  • Coltan is known as the blood-metal of Africa.
  • Coltan, as the key component in endoskeleton alloys, was a concept first introduced in TSCC, though the production team for Terminator Salvation mistook this for canon established in the original movies and therefore included coltan as the alloy for the T-800s in their movie.
