Red Brass (UNS C23000) – Composition, Properties And Uses

Red Brass Composition

Red Brass UNS C23000 is an alloy consisting primarily of copper (85-89%), zinc (5-9%), lead (0.5-2%), tin (0.2-1.5%), and trace amounts of iron and arsenic. It also contains traces of other metals, such as phosphorus and aluminium. This combination creates a strong material with excellent corrosion resistance and good machinability.

Red Brass Chemical Properties

The main elements that makeup Red Brass UNS C23000 are copper (Cu), Zinc (Zn), lead (Pb), tin (Sn), iron (Fe), arsenic (As), phosphorus (P), and aluminum (Al). Copper is the primary component in this alloy; it makes up 85-89% of its composition by weight. Zinc contributes 5-9%, while lead makes up 0.5-2%. Tin contributes 0.2-1.5%, while iron contributes trace amounts along with arsenic and other elements such as phosphorus and aluminium, which make up minor fractions of the total composition by weight. These various elements give this alloy its unique characteristics – strength combined with excellent corrosion resistance and good machinability.

Red Brass Mechanical Properties

Red Brass UNS C23000 has a tensile strength range between 50 to 80 ksi depending on the cold work applied during the manufacturing process; it also has a yield strength range between 25 to 45 ksi depending on the cold work applied during the manufacturing process; it has an elongation rate between 20%-40%, again depending on the cold work applied during the manufacturing process; it has a Brinell Hardness number between 90 to 140 BHN; it also has a Rockwell hardness number ranging from 30 HRC to 40 HRC; finally it has an ultimate shear stress value between 16 ksi to 28 ksi depending on the cold work applied during the manufacturing process. All these values can vary slightly depending on how much cold working was done during the manufacturing process before final product delivery, so always check with your supplier for exact values before proceeding with any project involving Red Brass UNS C23000 use.

Red Brass Physical Properties

Red Brass UNS C23000 has a melting point range of 1900°F – 2000°F or 1038°C – 1093°C depending on the exact composition of each particular batch produced by different suppliers, but generally speaking, they all stay within this temperature range; it also has an electrical conductivity rating between 16% IACS – 25% IACS at 68°F or 20°C room temperature. Finally, this material's thermal conductivity rating is around 185 BTU/hr/ft²/ft/°F or 100 W/mK at 68°F or 20°C room temperature.
