Among the copper alloys, white copper is widely used in shipbuilding, crude oil, chemical industry, construction, electric power, precision instruments, medical machinery, musical instrument production and other departments for corrosion resistance due to its excellent corrosion resistance and easy shaping, processing and welding. parts. Some white copper tubes also have special electrical properties and can be made into resistance elements, thermal resistance materials and compensation wires. Non-industrial-grade white copper tubes are mainly used to make decorative crafts.
Application advantages of white copper tube
Adding nickel to the white copper tube can significantly improve the strength, corrosion resistance, strength, resistance and thermoelectricity, and reduce the temperature coefficient of resistance. Therefore, compared with other copper alloys, white copper has excellent mechanical and physical properties, good ductility, high hardness, beautiful color, corrosion resistance, and rich deep drawing performance. It is widely used in shipbuilding, petrochemical, electrical appliances, instruments, medical machinery, Daily utensils, artworks and other fields, and it is also an important resistance and thermal resistance alloy.
The white copper tube is characterized by good mechanical properties and corrosion resistance, and beautiful color. Among the structural cupronickel, B30, B10 and zinc cupronickel are commonly used. In addition, there are also aluminum-nickel-nickel, iron-nickel-nickel and niobium-nickel-nickel. Zinc can be dissolved in a large amount in copper and nickel, resulting in solid solution strengthening and corrosion resistance. Zinc-nickel copper can be smoothly cut into various precision parts after adding lead, so it is widely used in instrumentation equipment and medical devices. This alloy has strong strength and corrosion resistance, good elasticity, beautiful surface, high quality and low price. Aluminum in aluminum cupronickel can significantly improve the strength and corrosion resistance of the alloy, and its precipitates can also produce precipitation hardening effects.
