CSMH firstly innovated the technology of diamond-based AlN with XRD (0002) rocking curve<3°, ultra-high thermal conductivity of diamond (thermal conductivity at room temperature can reach 2000W/m.K), Ra <2nm, contributing to a brand new application of AlN.

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.
