I havn't seen a composite of diamond and copper before. Heard plenty of yapping about plating and a solid diamond, but nothing like this.
They claim:

currently up to over 3 mm in thickness, 50 mm diameter wafers with 90 mm diameter wafers available in the near future.

Which is not good for water blocks nore heat sinks. 3mm thick is useless for CPU heatsinks and near usless for water blocks. I don;t see anything saying it can be milled easily? And what is the "real" cost of it? Surely not cheap...
Also:
Quote:
Metallization; HeaThru can be metallized for direct bonding with heat pipes, heat sinks or even the chip die

Maybe AMD and Intel could use this for a heat spreader!
