Introduction to Nickel Nickel Copper What is the material of Nickel Nickel Copper? Answer: It is a copper alloy sheet. Copper and its alloys are an indispensable material in industry. Pure copper and copper alloys containing different metal elements have different characteristics to meet different needs. Category of copper-nickel: zinc-nickel, nickel-nickel, nickel-nickel, zinc-nickel, with beautiful color, good ductility, fatigue resistance, corrosion resistance, rich deep drawing performance, use: widely used in antennas, crystal resonator shells, mobile phone shields , optical instruments, silverware, jewelry, zippers, keys, sliders for potentiometers, medical machinery, construction, wind instruments, keys, etc. Complex cupronickel: A cupronickel alloy with additions of manganese, iron, zinc, aluminum and other elements is called complex cupronickel (i.e. cupronickel with more than three elements), including iron cupronickel, manganese cupronickel, zinc cupronickel and aluminum cupronickel. In complex white copper, the second main element symbol and the component number group other than the copper content indicate the content of various elements. For example, - indicates that the nickel content is about 3 and the manganese content is about 3. Complex cupronickel has a model: ① Iron cupronickel: models include B, B, and B. The amount of iron added in iron-nickel copper is not more than that to prevent corrosion and cracking. It is characterized by high strength and its ability to resist corrosion, especially the corrosion of flowing seawater, can be significantly improved. Sales and transportation team ② Manganese white copper: Models include -, B.,. Manganese white copper has a low temperature coefficient of resistance, can be used in a wide temperature range, has good corrosion resistance, and has good processability. ③Zinc-nickel copper: Models include,,, (b), (b). Zinc-nickel copper has excellent comprehensive mechanical properties, excellent corrosion resistance, good cold and hot processing formability, and is easy to cut. It can be made into wires, bars and plates, and is used in the manufacturing of instruments, meters, medical equipment, daily necessities, communications and other fields. Precision parts. ④Aluminum cupronickel: model number is BB. It is an alloy based on copper-nickel alloy and added with aluminum. The density is .3. The properties of the alloy are related to the ratio of the amount of nickel to the amount of aluminum in the alloy. When:, the properties of the alloy. Commonly used aluminum-nickel copper includes, etc., which are mainly used for various high-strength corrosion-resistant parts in shipbuilding, electric power, chemical industry and other industrial sectors. Ordinary cupronickel: Copper-nickel binary alloy (i.e. binary cupronickel) is called ordinary cupronickel. In ordinary white copper, the letter B indicates the content of added nickel, such as: B indicates that the nickel content is approximately, and the rest is approximately copper. Models include B., B, B,. Industrial white copper: Industrial white copper is divided into two categories: structural white copper and precision resistance alloy white copper (electrical white copper). , Structural white copper: Structural white copper is characterized by good mechanical properties and corrosion resistance, and beautiful color. Among structural cupronickel, the most commonly used ones are BB and zinc cupronickel. In addition, there are aluminum-nickel copper, iron-nickel copper and niobium-nickel copper. Corrosion resistance in white copper, but more expensive. The performance of aluminum-nickel copper is close to that of aluminum-nickel copper, and the price is low, so it can be used as an excellent substitute. Zinc-nickel copper has been produced and used in China since the 19th century and is called Chinese silver. The so-called nickel silver or German silver also belongs to this type of zinc-nickel copper. Zinc can be solid dissolved in copper and nickel in large quantities, producing solid solution strengthening and resisting corrosion. After zinc-nickel copper is added with lead, it can be smoothly cut and processed into various precision parts, so it is widely used in instruments and medical devices. This alloy has high strength and corrosion resistance, good elasticity, beautiful appearance and low price. The aluminum in aluminum-nickel copper can significantly improve the strength and corrosion resistance of the alloy, and its precipitates can also produce precipitation hardening.
