Technology Metals

A loose grouping of metals used in small quantities in electronics and advanced manufacturing.

Definition

Metals essential for high-tech applications including electronics, semiconductors, renewable energy, and advanced manufacturing. Technology metals overlap significantly with critical minerals and include indium, gallium, germanium, rare earths, and tellurium.

Where people go wrong

Among the vaguest terms in the sector, and frequently applied to a deposit to borrow a narrative. Ask which metal, what the market for it is, and who buys it — several trade in markets too small and opaque to support a mine.
