Iridium (Ir) is a dense, silvery-white transition metal belonging to the platinum group metals (PGMs), prized for its exceptional corrosion resistance, high melting point, and outstanding hardness. It is employed in demanding aerospace, chemical processing, and high-temperature applications where extreme durability and chemical inertness are non-negotiable; engineers select iridium when conventional materials fail due to oxidation, corrosion, or thermal degradation, though its scarcity and cost typically limit use to critical-path components or small high-value parts.
