Making diamond an engineering material
Last verified:
We grow high-purity diamond wafers for advanced hardware. Used in data centers, aircraft, spacecraft, RF electronics, power devices, and lasers, our diamond moves heat up to 5× better than copper, helping critical systems run cooler, faster, and more reliably. Diamond has spent centuries as a symbol. We are turning it into infrastructure.
