CVD diamond has the highest elastic modulus, the highest sound propagation rate, the highest hardness, low density, good acoustic damping characteristics, low specific gravity, high fidelity, excellent high frequency response characteristics, and diamond has high thermal conductivity, so it is the best material for CVD diamond diaphragm high fidelity speaker treble diaphragm.

With excellent physical and chemical properties, diamond has broad development prospects in ultra-precision machining, semiconductor, aerospace, nuclear energy and other high-tech fields, and has even become an irreplaceable raw material in many fields. Single crystal diamond has the best thermal conductivity among all materials (up to 2200W/m.k), as well as high stiffness, considerable wear resistance and extremely high hardness, as well as chemical inertia, radiation resistance and excellent electrochemical performance.
