C28000 copper alloy, also known as brass, is a binary alloy composed of copper and zinc. Its copper content is usually between 60% and 70%, while its zinc content is between 30% and 40%.C28000 copper alloy is widely used in the manufacture of a variety of mechanical parts, building materials, and decorative items due to its excellent mechanical properties and outstanding workability.
Excellent Properties and Characteristics
HIGH STRENGTH AND HARDNESS: C28000 copper alloy has good strength and hardness, and can withstand large mechanical stress.
Good plasticity: the alloy has excellent ductility and plasticity and is easy to be cold worked and hot worked.
Excellent electrical and thermal conductivity: Brass has good electrical and thermal conductivity, making it widely used in electrical and heat exchange equipment.
GOOD CORROSION RESISTANCE: C28000 copper alloy shows good corrosion resistance in atmospheric and freshwater environments.
Performance in various environments
CORROSION RESISTANCE: C28000 copper alloy exhibits good corrosion resistance in atmospheric and freshwater environments, but its corrosion resistance decreases in seawater and chlorine-containing environments.
CORROSION RESISTANCE: The alloy exhibits good corrosion resistance in general industrial atmospheres, but in environments containing sulfides and chlorides, its corrosion resistance is compromised.
High-temperature performance: C28000 copper alloy can still maintain a certain degree of strength and hardness at high temperatures, but its mechanical properties will be reduced as the temperature rises, and it is usually used with the best effect below 300℃.
