Hmmm....the next step in the Cascades evolution? Where to go from here? This stuff supposedly boasts a rating of up to 1200 W/m*K. If it's all they say it is I imagine lateral heat spread would improve quite a bit. Not easily machinable tho'. Here is a responce from them regarding a few questions I had.

"Knoop Hardness is around 60 GPa, depending on DiaCu-II formula used. Lower diamond volume percentage DiaCu-II versions can be machined with wire-EDM, however, normally DiaCu-II must be laser-cut. Typically we provide machining and metallization services for our customers. DiaCu-II is not permeable to water; as far as creating a water seal, our current samples are shipped with a minimum 0.25mm layer of O-Free Cu on both flat sides of the DiaCu-II disks – so, assume that a seal would be created against the desired finish of the copper or any external plating/sputtering on top of the copper. Factory finish is fine-lathed OFHC copper surface, but can be mirror polished if desired (Cu is fairly easy to lap for most any customer). 90mm slugs will be available by Q2’04, depending on demand."

I did not get a quote so pricing is up in the air. It'd be fun to play with though.
