Platinum Alloys

Description

Platinum alloys are alloys made by mixing platinum with other metals, such as palladium, rhodium, yttrium, ruthenium, cobalt, osmium, copper, etc. Different elements act differently on platinum alloys, for example, the elements that have a strong influence on the temperature coefficient of its resistance are molybdenum, tungsten, ruthenium, silver. The alloying elements that have a strong influence on the hardness of platinum are nickel and ruthenium. The alloys composed of platinum, iridium, rhodium and refractory are the most commonly used alloying elements. In addition to the most common application in jewelry, platinum alloys can be used as functional materials, such as temperature measuring materials, catalysts, electrical contact materials, electrode materials, elastic materials, water magnetic materials, etc.

Platinum Alloy Products

• Platinum-Rhodium Alloys

Platinum (Pt) is a valuable precious metal. So is rhodium (Rh). Platinum-Rhodium alloys are valuable alloys that have some great properties, including stability at high temperatures. This could explain why Platinum-Rhodium alloys are used in many devices and parts in testing, aerospace and production lines.

Alfa Chemistry provides high-quality Platinum-Rhodium alloys in the shapes of wire, Wollaston wire, foil, tube, etc. We can also customize various shapes of Platinum-Rhodium products according to your requirements or drawings.

• Platinum-Iridium Alloys

Platinum–Iridium (Pt-Ir) alloys are alloys of the platinum group precious metals platinum and iridium. When added to platinum in small quantities, iridium will increase platinum's hardness—while in larger amounts, iridium can cause the metal to lose its ductility. In addition to jewelry, Platinum-Iridium alloys can be used in pacemakers, electrical contacts, spark plugs, electro explosive devices, medical leads and electrodes, thermistors, catalytic applications, pen points, surgical pins and pivots.

Alfa Chemistry provides high-quality Platinum–Iridium alloys in the shapes of wire, insulated wire, foil, rod, tube, etc. We can also customize various shapes of Platinum–Iridium products according to your requirements or drawings.

• Platinum-Tungsten Alloys

Platinum-Tungsten (Pt-W) alloys are platinum-based alloys with the addition of tungsten. Platinum-Tungsten alloys are excellent precious metal strain materials with the advantages of high tensile strength, high resistivity and resistive strain sensitivity coefficient, low resistance temperature coefficient and excellent oxidation resistance. Applications suitable for platinum-tungsten (specifically Pt92W8) include, but are not limited to, radiopaque spacers in embolization devices and potentiometer applications.

Applications

The interest in platinum alloys increases constantly, because the new areas of application are continuously discovered. Today, platinum alloys, due to their characteristics such as high strength, good workability and mostly corrosion resistance at high temperatures, are present in different areas such as production of glass and nitrogen fertilizers, production of thermocouples, production of automotive catalysts, jewelry and so on.
