Rhodium (Rh) is a precious transition metal from the platinum group, valued for its exceptional corrosion resistance, high melting point, and catalytic activity even at elevated temperatures. It is widely used in automotive catalytic converters, chemical processing catalysts, and plating applications where resistance to oxidation and chemical attack is critical. Engineers select rhodium for extreme-environment applications where alternatives would degrade, though its high cost and scarcity make it a selective choice reserved for high-performance or irreplaceable functions.
