WebApr 4, 2014 · Thermal Properties Applications Introduction 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 specific strength is a material's (or muscle's) strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa⋅m /kg, or N⋅m/kg, which is dimensionally equivalent to m /s , though the latter form is rarely used.
