More info

Molybdenum disc includes pure molybdenum disc and coated molybdenum disc. Coated molybdenum disc is PVD or evaporation with Ruthenium (Ru), Rhodium (Rh), Nickel (Ni), Silver (Ag), Gold (Au), etc. Molybdenum discs are widely used as contact materials in silicon-controlled rectifier diodes, transistors, and thyristors. Molybdenum has similar coefficients of thermal expansion (CTE) to silicon combined with moderate thermal conductivity and is therefore appropriate for large area power devices where considerable heat is generated. Additional applications include the utilization of molybdenum as heat sink bases in IC’s, LSI’s, and hybrid circuits.

Heeger Materials (HM) is a trusted supplier of pure Molybdenum and Molybdenum alloy. We offer Molybdenum discs in various sizes. Other shapes are also available upon request.
