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 parts Industrial : Brazing Rod, Welding Rod Available Sizes: Custom Diameter & Sizes, Random Mill lengths Available Products (forms): Round bars, Flat bars, Square bars, Rectangular bars, Hexagon bars Custom 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: Balance Note: Copper plus additions equal 99.50% minimum. Typical Physical Properties: Specific Gravity: 8.80-8.90 g/cm3 Coefficient 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. International Specification: Rods/Bars/Plates/Sheets: UNS.C64700, UNS.C70250, RWMA Class 3 European Standards: CuNi2Si, DIN 2.0855, CW111C to EN Note: ASTM: American Society for Testing and Materials RWMA: Resistance Welder Manufacturers' Association Note: Unless otherwise specified, material will be produced to DIN & RWMA. Mechanical Properties: The detailed Mechanical Properties will be available on request from customers.
