What is C26000 metal?
C26000 Cartridge Brass, also known as 70/30 brass, is a copper-zinc alloy containing approximately 70% copper and 30% zinc. It is renowned for its excellent cold working properties, good corrosion resistance, and high ductility. Due to its outstanding formability and machinability, C26000 is one of the most widely used brass alloys in sheet, strip, and tube production.

Fabrication & Manufacturing of C26000 Brass
These properties make C26000 a top choice for forged brass components that require both strength and ductility.
Cold Workability: Excellent (deep drawing, stamping, spinning)
Hot Forming: Good, typically forged at 700–800 °C
Machinability: Fair (rated ~30 compared to free-cutting brass = 100)
Joining: Excellent for soldering and brazing, fair for welding
Corrosion Resistance: Good in normal atmosphere, seawater, and industrial environments

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.
