The production process and product advantages of C10200 copper plate are as follows:

1. Production process

Smelting and casting

The raw material is high-purity electrolytic copper (copper content ≥99.95%), which is smelted at high temperature to form a uniform liquid alloy, and the oxygen content is strictly controlled (≤0.03%) to avoid hydrogen embrittlement.

During casting, the molten copper liquid is injected into the mold, and after cooling, an ingot or casting is formed. Sand casting, metal mold casting or continuous casting can be used.

Heat treatment

Annealing: The temperature range is 375-650℃, which is used to eliminate processing stress, improve ductility, and adjust the grain structure to optimize performance.

Solution treatment: Enhance the strength and corrosion resistance of the copper plate. For example, through cold processing (such as rolling, stretching) combined with annealing process, the tensile strength can be increased to 220-350 MPa.

Processing and forming

Through forging, rolling, stretching and other processes, the ingots are processed into plates, bars, pipes, etc., supporting cold/hot plastic processing, with a thickness range of 0.1-100mm and a width of up to 2500mm.

Surface treatment includes polishing, grinding, anodizing, etc. to ensure that the product is flat and free of sand holes and pores.

2. Product advantages

Excellent physical properties

High electrical conductivity and thermal conductivity: electrical conductivity ≥97% IACS (some data are 99% or higher), thermal conductivity 391 W/(m·℃), suitable for high-power current transmission and heat dissipation scenarios.

Stable low-temperature performance: still maintain good ductility and impact resistance in low-temperature environments.

Excellent processing performance

Excellent plasticity, supporting complex forming processes such as cold pressing, hot pressing, stamping, drawing, etc., and customizable sizes (such as thickness 0.1-100mm, width 200-600mm).

Excellent welding performance, can be used TIG welding, MIG welding and other methods, high joint strength and good airtightness.

Corrosion resistance and long life

The oxygen-free copper characteristics make it resistant to embrittlement in reducing gas environments (such as hydrogen), and the corrosion resistance is suitable for marine environments and chemical equipment.

The surface oxide film is beautiful and durable, and the life of some applications (such as building roofs) can reach 100 years.

Wide range of applications

Electrical and electronic: used for electric vacuum devices (such as magnetrons, traveling wave tubes), cables, brushes, etc., to avoid intergranular cracks caused by hydrogen.

Aerospace and automotive: high purity and high strength characteristics meet the needs of precision components, such as central solenoid coils and PF coils.

Construction and industry: roof copper plates, pipes, pressure vessels, etc., both functional and decorative.
