C12000 copper coil production process and product advantages:

1. Production process

Deoxidation treatment and alloy preparation

C12000 belongs to phosphorus deoxidized copper (DLP). It is refined by adding trace phosphorus elements to effectively remove oxygen from the copper liquid and reduce the impurity content (≤0.02%). This process avoids the problem of electrolytic roughness caused by impurities in ordinary red copper, and improves conductivity and processing accuracy.

Forming process

Hot rolling and cold rolling: C12000 can be processed into plates, strips, pipes, etc. through hot rolling, cold rolling and forging processes. For example, copper pipes are manufactured using seamless processes and meet ASTM standards.

Continuous casting and planetary rolling: China's copper processing technology uses continuous casting technology to achieve automated production. The single coil billet is heavy and long, and direct cold processing shortens the process; planetary rolling technology eliminates heating and extrusion steps, which is energy-saving and efficient.

Precision processing: Some manufacturers provide secondary processing services such as bending, welding, and cutting to meet customized needs.

Heat treatment specifications

Annealing temperature range is 400-650℃, hot working temperature is 800-900℃, to ensure stable material performance.

2. Product advantages

Excellent electrical and thermal conductivity

C12000 conductivity ≥97%IACS, although it contains phosphorus, the residual phosphorus is strictly controlled, and the conductivity is still better than ordinary red copper, suitable for electro-etching and high-precision molds.

High purity and low impurities

Impurity content ≤0.02%, reducing the surface roughness of electro-etching, improving processing efficiency and finished product gloss, and reducing subsequent polishing costs.

Excellent processing performance

Excellent weldability and cold bending performance, no tendency to "hydrogen disease", suitable for processing in reducing atmosphere environment.

Easy to process into various forms such as pipes, plates, wires, etc., to meet complex industrial needs.

Corrosion resistance

Good corrosion resistance in room temperature atmosphere, fresh water and seawater, especially suitable for marine environment (such as anti-biological attachment), but need to avoid contact with corrosive media such as sulfides and nitric acid.

Stable mechanical properties

Tensile strength 245-345MPa, elongation ≥8%, hardness 75-120HV, with both strength and ductility, suitable for high-demand fields such as aerospace and automobile manufacturing.

Economic benefits and environmental adaptability

Compared with other high-performance alloys, C12000 is more cost-effective and can adapt to a variety of environments (including reducing atmospheres), supporting sustainable manufacturing.
