C65300 is a silicon bronze alloy primarily composed of copper (Cu) with significant additions of silicon (Si: 2.0–4.0%) and manganese (Mn: 0.5–1.5%), alongside minor elements such as zinc (Zn: 0.05–1.5%), iron (Fe: 0.08–2.0%), and nickel (Ni: 0.01–0.6%) . This alloy is renowned for its high strength, excellent corrosion resistance, and good electrical conductivity, making it suitable for applications like electrical connectors, split bolts, and components requiring durability in harsh environments

C65100 is a low-silicon bronze alloy composed primarily of copper (Cu ≥ 99.5%) with silicon (Si: 0.8–2.0%) and trace elements such as iron (Fe ≤ 0.8%), zinc (Zn ≤ 1.5%), and manganese (Mn ≤ 0.7%) . It is renowned for its exceptional combination of strength, ductility, corrosion resistance, and electrical conductivity, making it ideal for demanding industrial applications.

C22000, commonly referred to as Commercial Bronze, is a copper-zinc alloy with a nominal composition of 90% copper and 10% zinc . Despite its name, it is technically classified as brass due to the zinc content but retains the historical designation "bronze"

C54400 copper wire is a free-cutting phosphor bronze, the main components of which are copper (Cu) and lead (Pb), and also contains zinc (Zn), tin (Sn) and other elements. This material is widely used in industrial fields due to its excellent cutting performance and good cold working performance, such as aviation, automobile, heavy machinery and other precision parts manufacturing, such as bushings, discs, sleeves and other seals.

C52100 is a phosphor bronze alloy, belonging to the tin phosphor bronze series, mainly composed of copper (Cu), tin (Sn) and a small amount of phosphorus (P). This material has high strength, good wear resistance and corrosion resistance, and is widely used in electrical connectors, springs, precision parts and other fields.
