In 1798, beryllium was discovered by Louis-Nicholas Vauquelin. It is a fairly soft metal, brittle in nature, with high specific heat, stiffness-to-weight ratio, strength-to-weight ratio and thermal conductivity. It can be easily rolled, machined, extruded, and drawn. The following datasheet gives an overview of beryllium.
