Molybdenum Hammer

Semiconductor grade single crystal furnace is an important crystal growth equipment in the single crystal silicon industry chain. At present, the Czochralski has the advantages of large single crystal quality, large diameter, low cost and high production efficiency, and has always been the main method for the preparation of semiconductor silicon substrates.

The hammer is usually made of tungsten and molybdenum materials as it is used in high temperature furnaces that require the materials to be heat resisting. It is mainly used to connect molybdenum seed holder and tungsten wire rope, and is hung on the suspension clamp or jumper the bottom, increasing the clamp vertical load heavy objects. Its concentricity requires to be the same as seed holder and tolerance is very strict.

The purity of the hammer is ˃99.95%, the concentricity with a tolerance ˂0.02 mm is the same as that of the molybdenum seed crystal chuck. The hammer can be customized upon requirement.
