what is the physical properties of berylliam?

Dear Charmi,

Beryllium has exceptional flexural rigidity (Young's modulus 287 GPa) and a reasonably high melting point. The modulus of elasticity of beryllium is approximately 50% greater than that of steel. The combination of this modulus and a relatively low density results in an unusually fast sound conduction speed in beryllium – about 12.9 km/s at ambient conditions. Other significant properties are high specific heat (1925 J·kg⁻¹·K⁻¹) and thermal conductivity (216 W·m⁻¹·K⁻¹), which make beryllium the metal with the best heat dissipation characteristics per unit weight. In combination with the relatively low coefficient of linear thermal expansion (11.4×10⁻⁶ K⁻¹), these characteristics result in a unique stability under conditions of thermal loading
