Due to its high strength, good thermal conductivity and thermal conductivity, and its similar expansion coefficient and good processing properties, it is used as a substrate material for silicon rectifier components and thyristor components (support for silicon wafers -- - molybdenum disc).
At present, the production methods of molybdenum discs are as follows:
1. Cutting Molybdenum rod with cutting machine
2. Direct pressing and sintering of molybdenum powder
3. Stamping molybdenum plate - machining. The molybdenum disc has high flatness, parallelism and smoothness, good intrinsic quality and surface tungsten defects.
In addition to Alkali washing, polished surface,we also can offer you mirror surface like below, we are always waiting here for you.
