17 Μαΐ 2022 · Physical and chemical properties. Physically, platinum is heavy, soft, malleable (easy to work—only silver and gold are easier to shape), and ductile (easy to draw into wires) and has a fairly high melting point (~1770°C or 3220°F). Chemically, it's often described as a noble metal because it is so unreactive.
