C61900 is an aluminum bronze alloy, mainly composed of copper (81.0%-88.0%), aluminum, iron, nickel and other elements. It has high strength, corrosion resistance and wear resistance, and is widely used in power, shipbuilding, machinery and other industries.

C62300 copper rod belongs to aluminum bronze alloy, with copper as the main chemical composition, and aluminum, iron and other elements as the auxiliary. The size range varies according to the product form, the diameter of the extruded rod may be up to 260mm, and the drawn rod or forging may be larger to 500mm. The international standard is mainly ASTM B150/B150M, which corresponds to the Chinese national standard GB/T 5231-2012.

C63200 (UNS C63200) is a high-performance nickel-aluminum bronze alloy primarily composed of copper (Cu), aluminum (Al), nickel (Ni), iron (Fe), and manganese (Mn).

Copper nickel/nickel silver rods are not made of silver, but rather copper, nickel, and zinc alloy rods that combine the good processability of copper with the corrosion resistance of nickel. They have a silver like color and are widely used in fields such as electronics, jewelry, and mechanical manufacturing.
