Product Description C64700 / C70250 Copper Nickel Silicon Alloys, including CuNi2Si copper bars,plates,wires.CuNi2Si - UNS.C64700/C70250 Nickel Silicon Bronze Alloys, which is an age-hardening alloy, higher alloyed in comparison with CuNi1.5Si, for current-carrying formed parts. It has an a-structure with very fine precipitations and recommends itself both for lead frames which require a high rigidity of the pins and for connector with high demands on the electrical conductivity, strength and relaxation behavior. In addition, the CuNi2Si can also be used for current-carrying formed parts and contact springs due to its good fatigue strength, forming and spring properties.Typical Application for C64700/C70250 Nickel Silicon Bronze Alloys:Electrical : Resistance Welding Electrodes, Motor Rotor Bar, And Resistance Welding Tips.Fastener : Fastener partsIndustrial : Brazing Rod, Welding RodAvailable Sizes:Custom Diameter & Sizes, Random Mill lengthsAvailable Products (forms):Round bars, Flat bars, Square bars, Rectangular bars, Hexagon barsCustom shapes are available upon request.Chemical Content, % NiMnFeSiCuOtherROHS DirectiveCdPbHgCr2---Bal-NDNDNDND Mechanical Properties Max Continuous Service Temp200oCResisivity at 20oC0.05±10%ohm mm2/mDensity8.9 g/cm3Thermal Conductivity<120Melting Point1090oCTensile Strength,N/mm2 Annealed,Soft140~310 MpaTensile Strength,N/mm2 Cold Rolled280~620 MpaElongation(anneal)25%(min)Elongation(cold rolled)2%(min)EMF vs Cu, μV/oC (0~100oC)-12Micrographic Structure austeniteMagnetic PropertyNon Application of CuNi2CuNi2 low resistance heating alloy is widely used in low-voltage circuit breaker, thermal overload relay, and other low-voltage electrical product. It is one of the key materials of the low-voltage electrical products. The materials produced by our company have the characteristics of good resistance consistency and superior stability. We can supply all kinds of round wire, flat and sheet materials.International Specification:Rods/Bars/Plates/Sheets: UNS.C64700, UNS.C70250, RWMA Class 3European Standards: CuNi2Si, DIN 2.0855, CW111C to ENNote: ASTM: American Society for Testing and Materials RWMA: Resistance Welder Manufacturers' Association Note: Unless otherwise specified, material will be produced to DIN & RWMA
