1. Produceable Materials and Implementation Methods

1. High-precision electrolytic copper foil: Produces products with a thickness of 6-105μm and Ra 0.1-0.3μm, used in PCBs and lithium battery electrodes. Adopts "multi-pass progressive polishing". The initially rolled copper foil is fed under tension control, and the diamond grinding pad is used for rough polishing with neutral polishing fluid, followed by 2-3 passes of fine polishing to reach the required roughness.
2. Oxygen-free copper strip / copper tube: Produces copper strips with a purity of ≥99.95% and Ra ≤0.05μm (for power transmission) and copper tubes with corrosion-free inner walls (for refrigeration and aviation hydraulics). The copper strip uses "double-sided synchronous polishing" and is treated with a wool felt roller and acidic polishing fluid; the copper tube adopts "simultaneous internal and external polishing" and operates at medium temperature in alkaline polishing fluid.
3. Copper alloy precision parts: Produces parts with Ra 0.08-0.1μm (such as brass bearings and connectors). Through a high-precision copper material polishing machine, diamond micropowder heads are used with anhydrous ethanol for polishing to improve grinding accuracy and polishing effect.

2. Application Industries and Key Roles

1. Electronic information industry: Assists in the processing of PCBs and connectors. Increases the signal rate of 5G PCBs by 15%-20% and ensures the stable operation of equipment.
2. Automobile manufacturing industry: Processes bearings. Reduces bearing wear by 30%.
3. Aerospace industry: Processes hydraulic pipelines, waveguide components, and instrument parts. Reduces pipeline pressure loss by 10%-15%, decreases satellite signal attenuation, and supports equipment research and development.
4. Power industry: Optimizes copper busbars, UHV equipment, and cable joints. Increases the conductivity of copper busbars by 5%-8%, avoids joint heating, and reduces power transmission failures.
