FAQ
| What is the electrical conductivity of C26000? It has an electrical conductivity of approximately 28% IACS (International Annealed Copper Standard). |
| Does C26000 rust or corrode? It does not "rust" (iron oxide), but it can corrode. It has good general corrosion resistance but can undergo dezincification in specific stagnant water conditions. Inhibited grades are available for such environments. |
| What is the density of C26000 brass? The density is about 8.53 grams per cubic centimeter (0.308 pounds per cubic inch). |
| C26000 vs C22000 brass - which is better for jewelry? C22000 (Commercial Bronze, 90% Cu) is often preferred for jewelry as it has a richer, more reddish-gold color closer to real gold and is highly resistant to tarnishing. C26000 has a lighter, more yellow gold color. |
| How to anneal C26000 brass? Anneal by heating to 425-650°C (800-1200°F) followed by rapid quenching in water or air cooling to soften the material for further cold working. |
| What is the typical yield strength of C26000? It varies by temper. For example, in the annealed state, the 0.2% yield strength is around 105-170 MPa, while in the spring temper, it can exceed 380 MPa. |
| Can C26000 be used for marine applications? It can be used in certain marine applications but with caution. For prolonged seawater exposure, more corrosion-resistant alloys like naval brass (C46400) or copper-nickels are preferred. |
| What is the thermal conductivity of C26000 brass? Its thermal conductivity is approximately 120 W/(m·K), making it a good material for heat exchangers and radiator components. |
Our factory
Our factory specializes in the production and manufacturing of high-quality copper products. We operate a comprehensive, end-to-end production line equipped with advanced continuous casting and rolling mills, precision drawing machines, high-speed rolling mills, and automated heat treatment systems. We professionally produce a wide range of copper tubes, plates, bars, wires, and foils. A strict quality inspection system is implemented throughout the entire process, from raw material intake to finished product delivery. Supported by precision instruments such as spectrometers, metallographic microscopes, tensile testing machines, eddy current flaw detectors, and laser dimension gauges, we ensure that our products fully comply with international and domestic standards-including ASTM, EN, JIS, and GB-in terms of chemical composition, mechanical properties, dimensional accuracy, and surface quality. We are committed to providing global customers with stable, reliable, and fully-specified copper material solutions.
copper product packaging
Our products are packaged using professional, customized industrial packaging solutions to ensure they remain intact during long-distance transportation and multiple handlings. For long products such as copper tubes and bars, we use sturdy waterproof wooden crates or metal-frame boxes for secure fixing and protection. Copper plates and foils are individually wrapped with anti-rust paper, then packed into steel-edged boxes or on pallets with reinforced hard corners. Copper wires are wound with moisture-proof film and neatly coiled onto custom-designed reels or placed in wooden cases. All packaging is clearly marked according to customer requirements with shipping marks, specifications, batch numbers, and handling symbols. Desiccants can also be placed inside the packages when needed, providing complete protection against rust, moisture, and impact throughout the entire journey from production to the destination port.
