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 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.
