What is C26000 metal?
C26000 as well as CuZn28 is combining excellent cold forming properties with good mechanical strength. CuZn30 has good hot forming properties and excellent soldering and brazing properties. Due to the outstanding deep drawing properties CuZn30 and the other two mentioned alloys are called "deep-draw" or "cartridge" brass.
Core Advantages
1. Deep Drawing Capability: Preferred for intricate shapes like cartridge cases.
2. Versatile Performance: Combines high ductility with moderate strength.
3. Corrosion Resistance: Suitable for indoor and mild outdoor environments.
4. Economic Efficiency: Optimal for high-volume manufacturing.
Product Applications
Ammunition: Cartridge cases, bullet jackets.
Hardware: Fasteners, springs, and hinges.
Plumbing: Valve components, fittings.
Electrical: Connectors, terminals, and shielding.
Decorative: Architectural trim, jewelry, and decorative hardware.

FAQs
Q1: Why is C26000 called "Cartridge Brass"?
A: It was historically used for ammunition cartridge cases due to its excellent cold-forming properties.
Q2: How does C26000 compare to C27000 (Yellow Brass)?
A: C26000 has higher zinc content (30% vs. 33%), offering better ductility but slightly lower corrosion resistance.
Q3: Can C26000 be used in marine environments?
A: Limited to short-term exposure; protective coatings are recommended for saltwater applications.
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.
