We are the main manufacturer and exporter of molybdenum discs. We have many years' experience in this field. We can make it according to customers' drawing, sample or sketch; free samples are available for testing, welcome you to contact me and hope to cooperate with your esteemed company! Application: Molybdenum discs are widely used as contact materials in silicon controlled rectifier's diodes, transistors and thrusters (GTO'S). Other than in specialist Applications, molybdenum are now accepted as the first choice mounting material for power semiconductor devices due to its significantly lower cost and weight. The fact that both materials have a similar coefficient of expansion to silicon combined with high thermal conductivity makes them an ideal choice, especially in large area power devices where considerable heat is generated. Further applications include the use of molybdenum as heat sink bases in IC'S, LSI'S and hybrid circuits
