Tungsten Disc and Square Disc for Semiconductors
We supply tungsten disc, washer and square for power semiconductors
Tungsten discs & squares are widely used as contact materials in silicon controlled rectifiers diodes, transistors and thyristors (GTO’S), it is only involved in specialist applications. Otherwise, molybdenum is the first choice mounting material for power semiconductor devices due to its significantly lower cost and weight.
Tungsten and molybdenum 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 and tungsten as heat sink bases in IC’S, LSI’S and hybrid circuits.
W discs and squares are cut from sheets and plates by saw or EDM cutting, they can also be punched.
Tungsten with larger thickness will be named as tungsten cylinder, we can also provide tungsten cylinder per request.
