What is C26000 metal?
GNEE supplies C26000 cartridge brass, sometimes also called brass or 260 copper alloy, in sheet and tube form. We offer a variety of sizes and can cut to your specifications. Of all brasses, C26000 has the best ductility and is used more frequently than any other copper-zinc alloy.
C26000 cartridge brass exhibits excellent corrosion resistance in most environments, but is not suitable for certain substances such as acetic acid, moist ammonia or ammonia compounds, hydrochloric acid, and nitric acid.

FAQ
| What is the difference between C2600 and C2680? Both are Japanese JIS designations for brass, but with different compositions and properties: C2600 (JIS): The direct equivalent to C26000. It is CuZn30 (70/30 brass) with excellent cold workability. C2680 (JIS): This is CuZn35 or 65/35 brass. It contains roughly 65% Cu and 35% Zn. This higher zinc content makes it slightly stronger and cheaper than C2600, but with reduced ductility and cold-forming capability. It is often used for simpler stamped parts, hinges, and plumbing fixtures where the highest formability is not required. |
| What is the melting point of C26000 brass? The melting temperature range is approximately 915-955°C (1680-1750°F). |
| Can C26000 brass be welded? Yes, it can be welded using gas tungsten arc welding (GTAW/TIG) and resistance welding, but it is more commonly joined by brazing or soldering for best results. |
| What is the hardness of C26000 in the hard temper? In the hard (H04) temper, C26000 typically has a Rockwell B hardness in the range of 55-75 HRB. |
| Is C26000 brass non-magnetic? Yes, like most copper alloys, C26000 is essentially non-magnetic. |
| 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. |
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.
