Almax PCD is wear resistant, heat resistant and electrically conductive polycrystalline diamond. With its’ Silicon binder, it has been developed to have a gain in signal for neutron measurements. The absorption lengths are much lower than PCD material with Cobalt binder.

Almax PCD cubes with truncated corners have been used in multi-anvil presses. Almax PCD has also found applications as shielding material (for high energy electron attenuation) or as seats for DACs.

Almax PCD is EDM cuttable and available in maximum size of 38 mm diameter by 26 mm height.
We can supply you PCD  cubes with truncated corners according to your drawing.
