Platinum Tube

Platinum Tube is a high-purity precious metal tube combining platinum's exceptional chemical inertness, high density, and thermal stability in a hollow form suited to the most demanding chemical and high-temperature applications. Its resistance to attack by virtually all acids and oxidizing environments — a consequence of its noble metal chemistry — together with a melting point of 1772 °C, a density of 21.45 g/cm³, and excellent dimensional stability under sustained thermal load, makes it the material of choice for components that must maintain integrity where base metals and most engineering alloys would fail or corrode. Its good ductility and machinability, despite its high density, allow tubes to be drawn to fine, precise dimensions without compromising structural integrity. Typical applications include thermocouple sheaths that protect thermocouple wire from chemical attack and mechanical damage in industrial and laboratory furnaces, and crucible and reactor liner components in chemical processing where molten salts, acids, or oxidizing atmospheres would degrade lesser materials. Its purity, corrosion resistance, and dimensional precision also make it well suited to precision scientific instrumentation, gas handling systems, and small-scale chemical apparatus where contamination-free performance is essential.
