Product Description Aurum- chromium alloy Au-Cr, AuCr2.1 resistance wireSpecificationsAuCr2.11,Factory supply with best price2,Diameter: from0.03mm-0.5mm3,Used in nonstandard thermocouple4, TCR: 0.000015,Resistivity : 0.33PtIr10Description.The alloy has been used in "nonstandard" thermocouples, electrical contacts and for electrodes in medical research. The alloy is harder and mechanically stronger than Platinum. This wire features a 90% Platinum and 10% Iridium composition and is widely used in the assembly of microelectrode probes. Iridium, a Platinum group metal, is very dense and hard, imparting added strength to the wire.PtIr 5,PtIr10,PtIr15,PtIr20,PtIr25 resistivity: 0.19-0.33 μOhm.mTechnical Data for Platinum/Iridium wire Electrical PropertiesElectrical resistivity ( μOhm.m ): 0.245Temperature coefficient ( K-1 ): 0.0013 Mechanical PropertiesElongation at break ( % ) <25Hardness - Brinell 130-190Tensile strength ( MPa )380-620 Physical PropertiesDensity ( g cm-3 )21.56Melting point ( C )1800 Thermal PropertiesCoefficient of thermal expansion @20-100C ( x10-6 K-1 )8.7Thermal conductivity @23C ( W m-1 K-1 )31 Typical Analysis : (ppm)Ag 100, Au 75, Cu 50, Fe 250, Ir 10%, Ni <100, Si <50, Pt. balance.
