What is C26000 metal?
260 Brass has fair to excellent corrosion resistance. Excellent cold workability; good hot formability. Brass alloys are copper zinc alloys which makes these alloys stronger and more durable than copper alloys. Alloys with high zinc levels are yellowish in color while those with less zinc start to turn reddish in color, and are sometimes called red brass.

FAQ
| What is the difference between C260 and C360 brass? This is a comparison between two fundamentally different brass alloys: C26000 (Cartridge Brass): A binary alloy of Cu (~70%) and Zn (~30%). It has excellent cold-forming properties (deep drawing, bending) but only fair machinability (rated ~20% of a free-machining brass). C36000 (Free-Cutting Brass): A leaded brass containing Cu (~61%), Zn (~35%), and Pb (~3%). The added lead improves machinability dramatically (rated at 100%, the industry standard). However, this comes at the cost of significantly poorer cold workability (it cracks if severely bent or stamped) and lower ductility. Choice: Use C26000 for formed parts. Use C36000 for parts that require extensive drilling, turning, or milling. |
| 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). |
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.
