How flexible is this diamond film? Will the diamond lattice crack when bent?

Our flexible CVD diamond is grown as an ultra-thin membrane (typically 10 to 50 microns). At this thickness, diamond exhibits remarkable mechanical flexibility, similar to thin glass fiber. It can be wrapped around curved heat pipes or integrated into foldable electronic designs without fracturing. We provide specific data on the minimum bending radius based on the film thickness to ensure long-term structural integrity in your application.

Why should I choose diamond film over high-performance graphite or copper foil

The primary advantage is the "Triple Crown" of thermal management: Unmatched Conductivity: With up to 1500 W/m.K, it exceeds the performance of high-end graphite and is 4x better than copper. Electrical Insulation: Unlike graphite or copper, diamond is a natural dielectric. This eliminates the need for additional insulation layers, which often act as thermal barriers. Heat Spreading: It excels at "in-plane" heat spreading, effectively eliminating high-temperature hot spots in high-density RF or
