C17500 copper strip and copper coil production process and product advantages:

Production process

Basic processing flow

The production of C17500 copper strip/coil mainly adopts the continuous extrusion process of copper alloy. The raw material Φ20 copper rod is heated and deformed by continuous extrusion method, and then cooled by circulating water to form billet. Some production processes also involve induction melting, vertical semi-continuous casting, hot rolling, cold rolling, bright annealing and other steps to ensure the high precision and uniform structure of the product. Specific processes also include quenching and tempering treatment (aging hardening), which significantly improves the strength, hardness and other properties of the material through solid solution and aging treatment.

Key process features

Cold/hot processing performance: C17500 has excellent cold processing performance and good hot processing performance. It can be processed into complex shapes by various forming methods such as rolling and stamping.

Heat treatment: After quenching, the material undergoes aging treatment (such as tempering) to precipitate strengthening phases, achieving high strength (tensile strength 794-1105 MPa), high hardness (Brinell hardness 220 HB or HRC 38-44) and other characteristics.

Surface treatment: Some processes include bright annealing to ensure excellent surface quality, suitable for precision electronic components.
