CoRh

CoRh is a cobalt-rhodium alloy that combines the high-temperature strength and corrosion resistance of cobalt with the exceptional oxidation resistance and catalytic properties of rhodium. This binary alloy is primarily used in high-performance applications requiring thermal stability and chemical inertness, particularly in aerospace, chemical processing, and catalytic converter systems where cobalt-based superalloys or pure rhodium would be cost-prohibitive or mechanically insufficient. The rhodium addition significantly enhances resistance to oxidative degradation at elevated temperatures while maintaining workability compared to pure rhodium, making it valuable for engineers balancing durability, thermal performance, and economic constraints.
