Tungsten's most notable property is its melting point of 3695 K (BP = 5828 K), the highest of any metal. Also of note is tungsten's tensile strength (∼ 2000–3500 MPa at 25°C) which is the highest of any metal above 1650°C. Tungsten has a body-centered cubic lattice ( a = 3.1648) for which it is the structure prototype.Web
