UNS C28000 brass, often known as Muntz metal, is a copper-zinc alloy composed of roughly 60% copper and 40% zinc. It was named after George F. Muntz, who invented the alloy in the early 1800s. C28000 brass is corrosion-resistant, machinable, and has high strength and ductility. Inconel may also be easily linked using soldering or brazing, making it appropriate for a wide range of applications.
The bright yellow color of UNS C28000 brass is one of its distinguishing characteristics, making it an appealing choice for decorative applications such as jewelry, ornaments, and architectural embellishments. It is also simple to process and can be molded, machined, and formed using a variety of techniques, including casting, extrusion, and forging, making it a versatile material for a wide range of tasks. Because of its high thermal conductivity, C28000 brass can be utilized to make industrial equipment such as heat exchangers and radiators. It is also fairly conductive, making it a popular copper alternative in electrical and electronic components.
UNS C28000 brass has better oxidation resistance. It is resistant to rust and other types of corrosion, particularly when exposed to air and moisture. However, like most copper alloys, it tarnishes with time due to oxygen and other atmospheric contaminants. It is critical to keep the surface of UNS C28000 brass clean and free of pollution in order to preserve its oxidation resistance.
Chemical Composition (%) of UNS C28000 Brass
UNS C28000 brass may include trace amounts of additional elements besides copper and zinc, such as iron and lead.

Features of UNS C28000 Brass
Applications of UNS C28000 Brass
Because of its high corrosion resistance and strength, UNS C28000 brass is frequently utilized in the electrical and electronic, construction, marine, and other industries.

| C28000 | 2.0360 | CuZn40 | C2801 | CZ109 | CW509L |
Machinability of UNS C28000 Brass
Because UNS C28000 brass is machinable, it can be easily cut, drilled, and shaped with a number of cutting equipment and processes. It's also very flexible, which means it can be easily bent, twisted, and stretched without cracking or breaking.
Weldability of UNS C28000 Brass
UNS C28000 brass is easily welded using various welding processes such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and resistance welding.
Corrosion Resistance of UNS C28000 Brass
For usage in less harsh maritime conditions, UNS C28000 brass has strong atmospheric corrosion resistance as well as good freshwater corrosion resistance. However, because it is prone to dezincification, UNS C28000 brass is not recommended for use in seawater or other highly corrosive conditions. Dezincification is a corrosion process that selectively removes zinc from brass alloys, leaving a weaker copper-rich structure that is prone to failure.
Despite its strength and longevity, brass is susceptible to stress cracking under certain conditions. Stress cracking in UNS C28000 brass can be caused by a number of factors, including corrosive conditions, high amounts of tensile stress, and fatigue cycles. Corrosive conditions, such as those containing chlorides or sulfur compounds, can weaken and shatter brass alloys. Stress cracking can also be caused by high amounts of tensile stress, such as those encountered during the production or installation of brass components. Similarly, fatigue cycles (repeated loading and unloading of brass components) can cause stress cracking over time. To avoid stress cracking in UNS C28000 brass, it is critical to carefully analyze the component's use and operating conditions. The use of corrosion-resistant coatings or inhibitors, as well as the proper selection of brass alloys, can help reduce the danger of stress cracking. Avoiding excessive levels of tensile stress and fatigue cycling will also aid in the prevention of stress cracking in C28000 brass.
