C17500 copper wire production process and product advantages:
1. Production process
Alloy composition and strengthening mechanism
C17500 is a beryllium cobalt copper alloy, the main components of which are copper (remainder), beryllium (0.4%-0.7%), cobalt (2.4%-2.7%), and trace amounts of iron, silicon, and aluminum. Its strengthening mechanism is aging precipitation strengthening, and the strength, hardness, and conductivity are improved through solution treatment and aging hardening treatment (quenching + aging).
Processing technology
Hot processing: It can be hot extruded, hot rolled, and forged, with excellent forming performance.
Cold processing: It has excellent cold processing performance such as cold rolling, stamping, and bending, and is suitable for high-precision parts manufacturing.
Welding performance: It supports a variety of welding methods, including soldering, laser welding, electron beam welding, etc., especially suitable for vacuum or high-voltage components.
Heat treatment: Solution treatment (softening temperature of about 1050℃) and aging treatment (softening temperature of 1000-1070℃) are key steps, which can significantly improve the tensile strength (up to 980MPa) and hardness (HRC 36-42).
