Rhodium Rods are versatile products from our wide range of specialized rods. They’re available in 16 variations, with a choice of diameters and lengths to suit different applications. Rhodium has excellent corrosion resistance, a high melting point and reflects light very well. All properties that make these rods ideal for use in laboratory equipment, electrical contacts, thermocouples, and as reflectors or plating in the glass and optical industries. The uniform diameter and precision manufacturing of our Rhodium Rods ensure consistency across scientific experiments and industrial processes.
