Copper Nickel Silicon Alloys
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 Rod
Available Sizes:Custom Diameter & Sizes, Random Mill lengths
Available Products (forms):Round bars, Flat bars, Square bars, Rectangular bars, Hexagon barsCustom shapes are available upon request.
Chemical Composition:
Ni: 1.60-2.20%Si: 0.40-0.80%Fe: 0.10% Max.Zn: 0.50% Max.Cu: BalanceNote: Copper plus additions equal 99.50% minimum.
Typical Physical Properties:Specific Gravity: 8.80-8.90 g/cm3Coefficient of Thermal Expansion per °C: 17 x 10-6 /K (20-300°C)Electrical Conductivity (% IACS): 38 (22 Ms/m)Thermal Conductivity (W/mk): 250 Modulus of Elasticity (10 3 MPA): 130
Note: 1). the units are based upon US Customary.2). the typical physical properties apply to age hardened products.
