Pure copper bars leverage the metal's crystalline structure with free electrons that enable exceptional electrical and thermal conductivity. The 99.999% purity ensures minimal impedance to electron flow, making them ideal for high-efficiency power transmission. In brass alloys (CuZn40Pb2), the zinc addition increases strength and machinability while maintaining good conductivity. The hot-rolled manufacturing process enhances grain structure for improved mechanical properties, while various tempers (soft annealed for formability, full hard for strength) allow optimization for specific applications. Copper's natural oxide layer provides corrosion resistance, ensuring long-term performance in harsh environments.
What is the difference between pure copper and brass rods?
Pure copper (99.999%) offers maximum conductivity, while brass (CuZn40Pb2) provides better machinability and strength with good corrosion resistance.
Can you produce custom sizes and shapes?
Yes, we offer full customization of thickness (2mm-200mm), width (10mm-600mm), length (200mm-6000mm), and various shapes including round and flat bars.
What surface treatments are available?
We provide mill, polished, bright, oiled, hair line, brush, mirror, and sand blast surfaces according to your requirements.
Do you provide material certifications?
Yes, all materials comply with international standards (JIS, ASTM, DIN, EN, ISO) and come with necessary certifications.
What is the minimum order quantity (MOQ)?
Please contact us for specific MOQ information as it varies by product type and customization requirements.
What payment terms do you accept?
We accept EXW, FOB, CIF, CNF, DDU, DDP trade terms with flexible payment options.
How does copper compare to aluminum for electrical applications?
Copper offers approximately 60% higher conductivity than aluminum, requires less space for the same current capacity, and provides better mechanical strength at connection points.
What is the lead time for production?
Standard products ship quickly, while custom orders typically require 7-15 days depending on specifications and quantity.
