Ruthenium (Ru) is a hard, silvery-white transition metal belonging to the platinum group metals (PGMs), prized for its exceptional corrosion resistance, high melting point, and catalytic properties. It is used in electronics, chemical catalysis, and specialized alloys where extreme durability and chemical inertness are critical; engineers select ruthenium when platinum is prohibitively expensive or when specific catalytic or wear-resistant properties are needed, though its high cost and limited availability restrict it to high-value applications.
