More info

Molybdenum discs are available in pure form or coated with materials such as Ruthenium (Ru), Rhodium (Rh), Nickel (Ni), Silver (Ag), Gold (Au), etc., using PVD or evaporation techniques. These discs serve as crucial contact materials in silicon-controlled rectifier diodes, transistors, and thyristors. With similar coefficients of thermal expansion (CTE) to silicon and moderate thermal conductivity, molybdenum is well-suited for large-area power devices that generate significant heat. Additionally, we offer Molybdenum Sputtering Targets.
