Thermal conductivity is as advertised. Machined into custom heat spreaders and tested ΔT within 2°C of our CAD simulation. Great material consistency from lot to lot

Love the warm reddish-gold hue straight out of the box. Hammered and textured beautifully without splitting. My sculptural installation pieces have never looked better

Requires ultra-flat surface for MRI shielding panels. Ran a profilometer test and got a flatness deviation under 0.02mm per 100mm length. Impressive quality for the price point.
