High-Quality Copper Bar: Reliable Power Transmission & Structural Excellence
Our copper bar (also known as copper busbar) is a high-performance metal product engineered to deliver exceptional conductivity, mechanical strength, and long-term durability—making it a cornerstone in power distribution, industrial machinery, and architectural projects globally. Crafted from high-purity copper and premium copper alloys, it meets strict industry standards to ensure consistent performance in even the most demanding environments.
Core Features & Material Advantages
- Exceptional Electrical Conductivity: Delivers superior current-carrying capacity, minimizing energy loss in power transmission systems. Outperforms alternative materials like aluminum, making it the top choice for high-efficiency electrical applications.
- Superior Mechanical Strength: Boasts excellent tensile strength and rigidity, ensuring structural stability in heavy-duty industrial setups and load-bearing architectural components. Resists deformation under high pressure or temperature fluctuations.
- Outstanding Corrosion Resistance: Naturally forms a protective oxide layer, safeguarding against rust, moisture, and chemical erosion. Maintains performance in outdoor, humid, or industrial environments with minimal maintenance.
- Excellent Thermal Conductivity: Efficiently dissipates heat generated during operation, preventing overheating in electrical panels, transformers, and industrial equipment. Extends the lifespan of connected components.
- Easy Fabrication: Highly machinable, allowing for precise cutting, drilling, bending, and welding to match custom project requirements. Compatible with various joining techniques for seamless integration into existing systems.
Product Specifications
- Alloy Options: Pure copper (C10100, C11000, T2, TU1), brass (C26000, C27200), bronze (phosphor bronze C51000, aluminum bronze C60800), and low-resistance copper alloys for specialized power applications.
- Dimensions:
- Cross-Section: Rectangular (thickness: 3mm – 100mm; width: 10mm – 300mm), square (5mm × 5mm – 150mm × 150mm), and custom profiles available.
- Length: Standard lengths 2m – 6m; custom lengths up to 12m or coil forms (for thin-gauge copper bars) on request.
- Hardness Grades: Soft (O), half-hard (H02), full-hard (H04), and extra-hard (H06) to suit different mechanical performance needs.
- Surface Finishes: Mill finish (natural copper luster), tin-plated (for enhanced corrosion resistance), silver-plated (for low-contact resistance), nickel-plated, and powder-coated (for color customization in architectural applications).
- Standards Compliance: ASTM B187, ASTM B249, JIS H3300, EN 13601, GB/T 5585.1-2019, ensuring compatibility with global industry requirements.
