C24000 is a high-performance brass alloy classified under the UNS (Unified Numbering System) designation. It is part of the Cu-Zn (copper-zinc) alloy family, optimized for applications requiring excellent cold and hot workability, mechanical strength, and corrosion resistance.

C23000, also known as Red Brass (85/15), is a copper-zinc alloy containing approximately 84.3–85% copper and 15% zinc, with trace impurities (e.g., Sn, Pb, Fe ≤0.01%)

C84400, classified as a leaded semi-red brass alloy, is a copper-based material renowned for its balanced combination of machinability, castability, and cost-effectiveness. It contains 78–82% copper (Cu), 6–8% lead (Pb), 7–10% zinc (Zn), 2.3–3.5% tin (Sn), and trace amounts of nickel (Ni), iron (Fe), and other elements . The inclusion of lead enhances pressure sealing and low-load bearing capabilities, making it ideal for plumbing, valves, and decorative fixtures .

C24000 is a brass alloy, mainly composed of copper (Cu) and zinc (Zn), belonging to the processing copper and copper alloy materials. It has the characteristics of high corrosion resistance, good mechanical properties and processing performance, and is widely used in hardware, machinery, construction, electrical and other fields, such as making gaskets, hexagonal bars, round bars, pipes, etc.

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"

C21000 is a brass alloy (copper-zinc alloy) with a copper content of 94–96%, zinc as the primary alloying element, and trace amounts of iron (≤0.05%) and lead (≤0.05%)

C36000 copper rod is a highly machinable lead brass alloy, widely used in precision machinery parts, automotive components, fasteners and other fields.

C22000, also known as Commercial Bronze, is a copper-zinc alloy primarily composed of 99.8% Cu with trace additions of Zn (≤0.1%), Pb (≤0.05%), and Fe (≤0.05%) . It is renowned for its distinctive bronze-like appearance, excellent cold and hot workability, and balanced mechanical properties.

C22000 is a copper-zinc alloy (brass) composed of 90% copper (Cu) and 10% zinc (Zn) . It is classified under the Unified Numbering System (UNS) as C22000, with equivalent designations including EN CuZn10 and DIN CW501L .
