The mechanical and physical properties of C71500 copper pipe are exceptionally good, with good ductility, high hardness, beautiful color and corrosion resistance. And easy to shape, process and weld. It is widely used in shipbuilding, petrochemical, construction, electric power, electrical appliances, precision instruments, medical equipment, daily necessities, handicrafts, musical instrument production and other fields
C71500 cupronickel is a copper-based alloy with nickel as the main additive element. It is silvery white with metallic luster, so it is called cupronickel. After the material is processed into a tubular shape, it becomes a cupronickel tube.
C71500 copper pipe is pure copper plus nickel. Can significantly improve the strength, corrosion resistance, hardness, electrical resistance and thermoelectricity, and reduce the temperature coefficient of resistivity. Therefore, compared with other copper alloys, C71500 copper tube has exceptionally good mechanical and physical properties, good ductility, high hardness, beautiful color, corrosion resistance, and good deep drawing performance.
