Production process and product advantages of C12200 copper rod:

1. Production process

C12200 copper rod mainly adopts the melting casting-extrusion process, and the specific process includes:

Raw material processing: Use raw materials such as electrolytic copper, copper, zinc ingots and copper bran, and enter the melting process after sorting.

Melting: Heat the raw materials to 1100℃ in an electric furnace to melt, add slag remover under normal pressure to remove impurities, and keep the molten state by insulation

Molding: Molten copper liquid is molded by a traction machine or a reverse extruder. Among them, the advanced process uses a 38MN reverse extruder, with a single ingot weight of nearly 1 ton, which can achieve high-density copper rod production.

Post-processing: Including drawing (removing surface debris), straightening, cutting and other steps. Some companies also improve accuracy through continuous casting and automatic control.

2. Product advantages

Excellent processing performance

The cold/hot plastic processing performance is excellent, and complex molding such as stamping, stretching, and bending can be performed.

The phosphorus deoxidation process (residual phosphorus 0.015-0.040%) significantly improves the resistance to hydrogen embrittlement and is suitable for reducing atmosphere annealing scenarios.

Good welding performance, supporting oxyacetylene welding, gas shielded arc welding and other processes.

High material quality

Purity ≥ 99.9%, dense and uniform structure, no pores or sand holes on the surface, and high flatness.

Through reverse extrusion and precision drawing technology, the product has high density (tensile strength ≥ 290MPa) and dimensional accuracy.

Wide applicability

Although the electrical/thermal conductivity is lower than that of oxygen-free copper (such as C10200), it still meets the industrial needs of air conditioning pipelines, heat exchanger tubes, oil pipes, etc.

It can be adapted to the needs of different industries through customized length (minimum order of 50 kg) and processing services (bending, cutting, etc.).

Environmental protection and efficiency

Short-process production processes (such as natural gas + electric heating) reduce energy consumption, and the scrap recovery rate is as high as 90%.

Continuous and automated production lines (such as computer control) improve production efficiency, and some companies have achieved same-day delivery.
