What is C28000 brass?
C2800 is a copper-zinc alloy brass grade that combines good mechanical properties with excellent machinability. It exhibits excellent plasticity in both hot and cold states, and demonstrates outstanding machinability, weldability, and corrosion resistance, although it carries a risk of corrosion cracking. Typical applications of this alloy include deep-drawn parts, radiator assemblies, and the manufacture of various standard parts such as rivets, washers, nuts, conduits, pressure gauge springs, and screens.

Our factory
We operate a modern, specialized copper production facility equipped with advanced continuous casting and rolling lines, precision CNC machining equipment, and a rigorous quality inspection system, focusing on the manufacturing of copper tubes, plates, rods, wires, and strips. The factory is ISO9001 certified and possesses a complete industry chain capability-from raw material smelting and precision processing to finished product sorting. With an annual production capacity of tens of thousands of tons, we can flexibly handle customized orders, ensuring that our products meet international standards in dimensional accuracy, mechanical properties, and surface finish.
Copper product packaging
We implement customized packaging solutions based on product characteristics: copper tubes and rods are wrapped with moisture-resistant kraft paper, reinforced with bundling, and secured on wooden pallets or iron frame boxes to prevent deformation and damage during transit. Copper plates and strips are covered with protective film, separated by foam padding between layers, and externally secured with steel strapping along with waterproof packaging. Wires are coiled on industrial reels or vacuum-packed with plastic film. All packaging includes clear labels indicating product specifications, batch numbers, and protective symbols, ensuring safe delivery during long-distance sea and land transportation.
