Live Rhodium (Rh) Scrap Price & Catalytic Converter Impact
Rhodium is the rarest and highest-value precious metal per gram in three-way catalytic converters, responsible for NOx reduction.
How Rhodium (Rh) Affects Catalytic Converter Scrap Value
Rhodium (Rh) is the most valuable precious metal in automotive catalytic converters on a per-gram basis, frequently trading at several times the price of Gold or Platinum. Its unique chemical property is its unmatched ability to reduce nitrogen oxides (NOx) into harmless nitrogen and oxygen gases without requiring excess fuel.
Even though a catalytic converter typically contains a smaller fraction of a gram of Rhodium compared to Platinum or Palladium, Rhodium's high spot price means that small differences in Rhodium loading (for example, 0.10g vs. 0.45g) can change a converter's scrap value by over $100. Ultra-low-emission gasoline converters (such as Toyota, Honda, Subaru, and BMW manifold catalysts) often derive 40% to 65% of their total intrinsic value from their Rhodium content alone.
