C26000 Yellow Brass Tube (70/30) contains around 70% copper and 30% zinc, with outstanding strength and resistance to corrosion. Its mechanical characteristics are a tensile strength ranging from 300–500 MPa, excellent ductility, and superior machinability. The advantages of the alloy are better workability, solderability, and weldability, together with high electrical and thermal conductivity. It possesses high resistance to dezincification, which is suitable for applications in marine, industrial, and decorative environments. Due to its balance between strength and elasticity, it becomes a favorite selection for many companies.
