Pure Copper Plate
Pure copper plate (commonly known as red copper plate or purple copper plate) refers to a flat copper sheet made from high-purity electrolytic copper through a rolling process. Its copper content is typically not less than 99.9%.
Its main applications are as follows:
1. Power electronics: Manufacturing busbars, conductive contacts, lead frames, and heat dissipation substrates.
2. Architectural decoration: Used in roofing curtain walls, pipe valves, utilizing its weather resistance and aesthetics.
3. Industrial manufacturing: Used in heat exchangers, vacuum devices, and structural components requiring good weldability.
Description
Pure copper plate (commonly known as red copper plate or purple copper plate) refers to a flat copper plate sheet made from high-purity electrolytic copper through a rolling process. Its copper content is typically not less than 99.9%.
Characteristics of Pure Copper Plate:
1. Excellent electrical and thermal conductivity: Pure copper plate has electrical and thermal conductivity second only to silver, and extremely low resistivity (approximately 1.68 × 10⁻⁸ Ω·m), making it the preferred material for power transmission and heat dissipation devices.
2. Excellent formability: The face-centered cubic crystal structure gives pure copper plate excellent ductility (annealed elongation ≥ 50%), making it easy to perform cold and hot working, bending, and deep drawing. However, its hardness is relatively low (HV approximately 40-100), making it prone to work hardening.
3. Good but limited corrosion resistance: Pure Copper Plate can form a dense oxide film on its surface in air, fresh water, and non-oxidizing acids to prevent further corrosion; however, its corrosion resistance is poor in sulfur-containing environments, seawater, or strong oxidizing acids, and it is prone to “hydrogen slag” under high-temperature reducing atmospheres.
4. Relatively low strength and high cost: Pure Copper Plate has relatively low tensile strength (approximately 200-250 MPa in the annealed state), making it unsuitable as a standalone load-bearing structural component; due to the scarcity of copper resources, its price is significantly higher than that of ordinary steel or aluminum alloys.
5. Pure Copper Plate has a purplish-red appearance, a density of approximately 8.9 g/cm³, a melting point of 1083℃, and good weldability, but it is prone to sticking to the cutting tool during machining. In practical applications, strength is often improved through cold working, or specific properties are improved by adding trace alloying elements.
Applications of Pure Copper Plate:
Pure Copper Plate, with its high electrical and thermal conductivity, excellent corrosion resistance, and good ductility, is primarily used in the following core areas:
Pure Copper Plate Applications in Electrical and Power Transmission:
1. Power Transmission: Pure Copper Plate is used to manufacture high-voltage/low-voltage cables, transformer coils, switch contacts, busbars, and connectors, utilizing its low resistivity to reduce power loss.
2. Grounding Systems: Pure Copper Plate is used as grounding copper busbars or flexible connection materials for lightning protection and safety grounding in substations, data centers, and new energy facilities.
3. New Energy Support: Pure Copper Plate is used as a current collector in lithium batteries and in charging piles and energy storage systems to fabricate high-current busbars, requiring a clean surface to ensure high welding yield.
Applications in Electronic Heat Dissipation and Semiconductor Industries:
1. Heat Dissipation Components: Pure Copper Plate is used as a heat dissipation substrate or embedded copper block for high-power LEDs, 5G base station power amplifier modules, and IGBT power modules, rapidly dissipating chip heat.
2. Precision Electronics: Pure Copper Plate is used to fabricate lead frames, vacuum electronic device cavities, waveguides, and high-frequency circuit boards. High-end applications require oxygen-free copper (purity ≥99.99%) to avoid high-temperature oxidation.
3. PCB Manufacturing: Pure Copper Plate serves as the core thermal conductive layer in metal-based circuit boards (MCPCBs), improving the thermal management efficiency of electronic devices.
Applications in Architecture and Decoration Engineering:
1. Roofing and Curtain Walls: Pure Copper Plate is used for high-end building roofs and wall decoration, forming a stable “copper oxide” passivation film to resist atmospheric corrosion, with a lifespan of over 100 years.
2. Interior Decoration: Pure Copper Plate is processed into doors, windows, screens, artworks, and antique finishes, showcasing rich textures through brushing, mirror finishing, or oxidation blackening processes.
3. Hydraulic Facilities: Used as waterstops in dams, tunnels, and factories, utilizing its plasticity to adapt to structural deformation and prevent leakage.
Applications in Industrial Equipment and Other Fields:
1. Chemical Corrosion Protection: Pure Copper Plate is used to manufacture evaporators, condensers, pipes, and valves, resisting corrosion from non-oxidizing acids, alkalis, and seawater.
2. Machinery Manufacturing: Pure Copper Plate is used in mold inserts, stamped parts, and wear-resistant gaskets; in some applications, cold working increases its hardness.
3. Specialized Fields: Involved in military detonator liner casings, musical instrument tubes, and refrigeration equipment components, leveraging its low-temperature non-brittleness properties.
