Platinium-Iridium Alloy Rod

Platinium-Iridium Alloy Rod

FANMETAL supply the Platinium-Iridium alloy such as Platinium-Iridium Alloy Rod PtIr10, PtIr25, PtIrNi , alloys in the shape of wire , sheet , tube , ball, cylinder.Platinum-iridium alloy is a classic electrical contact material, used for aero engine ignition contacts, high-sensitivity relays and electrical contacts of micro-motors; potentiometers, conductive rings, and brushes for precision sensors such as aircraft, missiles, and gyroscopes.

Platinum-iridium alloy is a platinum-based binary alloy containing iridium, including Ptlr10, Ptlr17.5, Ptlr25, Ptlr30 and other alloys, which have high hardness, high melting point, high corrosion resistance and low contact resistance.Platinum-iridium alloy has high chemical stability, excellent mechanical and electrical properties, high temperature resistance, oxidation resistance, wear resistance, high temperature creep resistance, and high catalytic activity. It is widely used in transportation, biomedical, energy, chemical industry, aviation aerospace and other fields.

Platinium-Iridium Alloy Rod Picture:

Platinium-Iridium Alloy Rod are widely used in modern industry and technology.

(1) Instrument materials: They are classic weak current contacts and conductive ring materials, high-reliability ignition materials for aero-engines, potentiometer windings and wire-tensioning materials for various precision instruments, sensors and micro motors, and thick films in microelectronics technology. Resistive materials, etc.

(2) Electrode materials in the chlor-alkali electrolysis industry.

(3) Dental materials and other medical materials.For example, it is used as a radiopaque marker in angioplasty and other minimally invasive catheter procedures.

(4) Standard resistance, weight and meter ruler materials.

(5) Due to its strong oxidation resistance and high melting point, it can also be used as temperature measurement materials and experimental equipment (such as high-temperature crucibles and other advanced chemical vessels).

(6) The pairing of PtIr10 alloy and AuPd40 alloy can be used as a middle-temperature thermocouple, and its stability is affected by the volatilization loss of iridium. In fact, Platinium-Iridium Alloy Rod with high iridium content are not suitable for long-term use at high temperatures. The iridium content of alloys widely used in industry is generally less than 30%. PtIr5 and PtIr10 are classic potentiometer winding materials, PtIr17.5 is a brush material, and PtIr25 is a highly reliable aero-engine ignition contact material. A variety of gold-based alloys have been used to replace platinum-iridium alloys as winding materials and brush materials, but PtIr25 alloys have not yet been reliably substituted.
