Description

Quick Detail:
C17410 (low beryllium cobalt) and C17460 (low beryllium nickel) is  precipitation-hardened copper alloy renowned for its exceptional balance of high strength, electrical/thermal conductivity, and corrosion resistance.

 

Key Characteristics & Advantages of C17410 and C17460:

C17410 is a low-beryllium, cobalt-alloyed copper strip compliant with ASTM B768  standards, featuring an optimal balance of high electrical conductivity and moderate mechanical strength. With a beryllium content of only 0.15%–0.50%, it avoids the high brittleness of high-beryllium copper alloys while retaining outstanding comprehensive performance. Its typical electrical conductivity reaches approximately 50% IACS, far superior to conventional high-strength beryllium copper grades. The alloy is supplied in pre-hardened tempers (TH02/1/2HT and TH04/HT), eliminating the need for secondary heat treatment and effectively preventing post-processing deformation and reducing production costs. It exhibits excellent cold bending formability, stable elastic performance, superior stress relaxation resistance, good solderability and weldability, as well as reliable corrosion and fatigue resistance. Its density is 8.80 g/cm³ with a thermal conductivity of 230 W/m·K, ensuring efficient heat dissipation in precision electronic components.
C17460 is a high-performance copper-nickel-beryllium wrought alloy strip, featuring higher mechanical strength, hardness and wear resistance compared with C17410, with slightly lower electrical conductivity (45% IACS). It possesses ultra-high tensile strength and yield strength after precipitation heat treatment, excellent anti-fatigue performance and creep resistance, and outstanding stress relaxation resistance under long-term high-load and high-temperature working conditions. The alloy shows excellent friction and wear resistance, non-galling properties and dimensional stability, with good hot and cold processing performance, including superior machinability, brazing and spot welding performance. It also delivers excellent corrosion resistance and structural rigidity, maintaining stable mechanical and physical properties in harsh industrial environments for long-term service.

Core Applications:
C17410 and C17460 strip is widely used in high-reliability industries. Benefiting from its high conductivity and reliable elasticity, C17410 strip is widely used in precision electronic and electrical industries that require both current-carrying capacity and structural stability. Typical applications include ultra-thin precision spring contacts, conductive terminals and connectors for consumer electronics, household appliances and automotive electronics. It is also ideal for manufacturing micro conductive shrapnels, low-load elastic components, precision machined electrical parts, and corrosion-resistant conductive structural parts. In addition, it serves as raw material for small-scale welding electrodes, precision instrument elastic accessories and miniature bearing components, fully adapting to high-precision, low-deformation and high-conductivity working scenarios.
