Unique Features:

The GB/T 5231 Copper Sheet is known for its high copper purity of 99.90%, which ensures excellent electrical conductivity (97% IACS) and thermal conductivity (390 W/m·K). This makes it ideal for applications where heat dissipation or electrical current efficiency is important. The copper’s low oxygen content (0.02%) enhances its resistance to oxidation, prolonging the material’s lifespan in harsh environments. The material is also highly malleable, meaning it can be easily formed, shaped, or welded to suit specific application needs. This makes GB/T 5231 Copper Sheet a versatile option in a wide range of industrial, electrical, and decorative applications.

Applications:

• Electrical Engineering & Electronics: GB/T 5231 Copper Sheet is used in the manufacturing of electrical conductors, cables, busbars, and connectors. Its high conductivity ensures low resistance, improving the efficiency of electrical systems.
• Heat Exchangers: Due to its excellent thermal conductivity, it is commonly used in heat exchangers, air conditioning, and refrigeration systems, where efficient heat transfer is essential.
• Plumbing & Water Systems: GB/T 5231 Copper Sheets are widely used for producing piping systems, valves, and other components where corrosion resistance and long-lasting performance are necessary, particularly in water and gas distribution systems.
• Architectural & Decorative Uses: Copper sheets are often used in architectural applications, such as roofing, facades, and decorative panels, because of their aesthetic appeal and the attractive patina they develop over time.
• Industrial Manufacturing: GB/T 5231 Copper Sheet is also used in the production of industrial components, such as transformer windings, motors, and other machinery, where high conductivity and durability are crucial.
