280 Brass Chemical Properties
C280 has excellent dezincification and atmospheric corrosion resistance due to its high copper content. It is also resistant to hydrochloric acid at room temperature concentrations up to 5%. However, it is not recommended for use in caustic solutions or environments with sulfur compounds due to the risk of sulfide stress corrosion cracking.
280 Brass C28000 Mechanical Properties
Because of its malleability and ductility, UNS C82000 Brass can be easily formed into complex shapes without losing strength or structural integrity. It has a tensile strength of 25-35 ksi (thousand pounds per square inch) and a yield strength of 20-30 ksi, making it suitable for heavy loads or applications that require high-stress levels.
One of the main advantages of brass C28000 is its ability to resist oxidation and wear at high temperatures. It has a melting point between 937°F – 1017°F (507°C – 550°C), depending on the alloying elements present in the material; this makes it suitable for applications involving extreme heat or friction such as bearings or gears in internal combustion engines.

280 Brass Thermal Properties
The thermal properties of the UNS C82000 copper alloy are tabulated below.
Due to its combination of properties—malleability, corrosive resistance, heat resistance brass 280 is often used in applications involving fluid flow systems such as pipes or pumps; valves; electrical components; automotive components; decorative objects; fasteners; fittings; castings; gaskets; nuts & bolts etc. It can also be used for bearing surfaces due to its low coefficient of friction which helps reduce wear on moving parts during operation.
280 Brass Corrosion Resistance
Brass 280 Alloy offers excellent corrosion resistance thanks to its high copper content. It prevents dezincification when exposed to water or other corrosive substances over time like most other alloys containing zinc. It also resists attacks from organic acids such as formic acid, acetic acid, and non-oxidizing mineral acids, including sulfuric acid in concentrations up to 15%.
280 Brass Heat Resistance
C28000 is one of the most versatile and dependable metals used in industrial applications – especially regarding heat resistance. With a melting point of nearly 1700 degrees Fahrenheit, Brass 280 is specially designed to retain its strength under extreme temperatures, making it an ideal material for constructing high-pressure equipment and parts exposed to harsh conditions. Its superior ability to resist oxidation makes it a perfect alloy for many industries, including energy production, chemical manufacturing and food processing. These qualities make Brass 280 the premier heat-resistant material on the market today.
280 Brass Heat Treatment
Heat treatment can be used on brass 280 if desired to improve its hardness or ductility but it should be done carefully since over-heating may cause embrittlement due to grain growth leading to cracks forming after cooling down again too quickly, which could compromise the structural integrity of the material if left unchecked. Generally speaking though, no heat treatment is necessary because the material already possesses good mechanical properties without any additional processing needed before use.
280 Brass Welding
Brass C28000 welding is a versatile and reliable method of joining two or more materials together. It’s suitable for many metals, such as brass, copper and stainless steel. During the process, an arc generates heat that melts the metal and binds it together. For best results, it must be performed in an area with a reduced airflow, ensuring no molten metal loss due to wind draft. The strength of the brass weld can be tailored by adjusting the wattage, oscillation speed and amperage levels—making this type of welding remarkably precise. With soldering products available at hardware stores and home improvement depots, Brass C28000 welding allows DIY enthusiasts to bring their projects to life in an economically friendly way.
