molybdenum disc copper cathodes 99.99% purity China 

 

Description:
Product name: Molybdenum Disc/Squares
Material: Mo >99.95%
Density: 9.2~10.2g/cc
Application:
Molybdenum Discs/Squares has a similar low coefficient of thermal expansion to that of silicon, and better machining properties. For that reason, it's usually used for heat dissipation as electronic component of high power and high reliability semiconductor, contact materials in silicon controlled rectifiers diodes, transistors and thyristors (GTO'S), mounting material for power semiconductor£¬heat sink bases in IC'S, LSI'S and hybrid circuits. 
Surface Finish:
The polishing surface and lapping surface are both available. 
Specification:
Molybdenum disc 7 ~ 100mm diameter, 0.25 ~ 4.0mm thickness .Molybdenum square 25 ~ 100mm diameter, 0.5 ~ 1.5mm thickness ,Flatness tolerance: <4um ,Roughness: Ra 0.8 .
