Tungsten Disc

Category:

We supply tungsten disc, washer and square for power semiconductors.
Tungsten disc & square 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 discs and squares are cut from tungsten sheets and plates by saw or EDM cutting, they can also be punched.
