Product Detail

Iridium Wire

Iridium Wire


Iridium Wire





Melting Point:



Thin filament

Physical Properties:

Silver white metal, hard and brittle. As long as hot processing, as long as no annealing, can be extended into filaments and thin sheet; once annealed, the loss of ductility becomes hard and brittle.

Chemical Properties:

Very stable chemical properties, does not dissolve in acid, slightly soluble in aqua regia; slightly affected by molten sodium hydroxide, potassium hydroxide and dichromate sodium erosion. Formed complexes with strong tendency. Main valence + 2, + 4 and + 6.

should be sealed in a dry, cool environment, should not be long exposure to the air, to prevent the occurrence of moisture aggregation, affecting the performance and effectiveness of the use of dispersion.

Main Applications:

Pure iridium is specially used in aircraft spark plugs, which are used for making scientific instruments, thermocouples, resistance wires and pen tips, etc.. Do the alloy, can enhance the hardness and corrosion resistance of other metals. Pure iridium is much used in alloys, although iridium is used alone, but such a situation is relatively small, in the form of dense metal like shape generally appear as spindle shaped, crucible, or silk. The iridium processing into filamentous high cost, the iridium wire of the market price of up to 1000 yuan per gram, so iridium often alloy forms appear, it with platinum formed (PT IR of the 10% and 90%) alloy, due to expansion coefficient is extremely small, commonly used to make international standard meter, world kilogram is also made of platinum iridium alloy produced.
