The main components of cupronickel, what are the types of cupronickel?

Cupronickel. It is a copper alloy with nickel as the main added element.

Copper-nickel binary alloy is called ordinary cupronickel; Copper alloys with manganese, iron, zinc, aluminum and other elements are called complex cupronickel. Industrial cupronickel is divided into two categories: structural cupronickel and electrical cupronickel. Structural cupronickel is characterized by good mechanical properties and corrosion resistance, and beautiful color.

This cupronickel is widely used in the manufacture of precision machinery, chemical machinery and ship components. Electrical cupronickel generally has good thermoelectric properties. Manganese copper, constantan, and copper are manganese white copper with different manganese contents, which are used to manufacture precision electrical instruments, rheostats, precision resistors, and strain gauges.

Materials for thermocouples, etc.

Cupronickel is a copper-based alloy with nickel as the main added element, which is silvery-white and has a metallic luster, hence the name cupronickel. Copper and nickel can be infinitely solid solution with each other, thus forming a continuous solid solution, that is, regardless of the proportion of each other, it is always a single-phase alloy. When nickel is melted into red copper, the content exceeds 16%, and the resulting alloy color becomes white as silver, and the higher the nickel content, the whiter the color.

The nickel content in cupronickel is generally 25%.

Cupronickel is generally divided into, foreign cupronickel, zinc cupronickel, aluminum cupronickel, iron cupronickel, manganese cupronickel, etc.

Iron White Bronze Grade:

Manganese cupro: BMN3-12,

Zinc cupro: BZN18-18, BZN18-26, BZN18-18, BZN15-12 (ZN).

Aluminum cupronickel: BAL13-3,

Ordinary white copper plate:.

Cupronickel is generally widely used in shipbuilding, petroleum, chemical, construction, electric power, precision instruments, medical equipment, musical instrument production and other departments as corrosion-resistant structural parts. Some cupronickel also has special electrical properties that allow it to be used to make resistive elements, thermocouple materials, and compensation wires. Non-industrial cupronickel is mainly used to make decorative handicrafts.

Complex cupronickel: Copper alloys with manganese, iron, zinc, aluminum and other elements are called complex cupronickel (i.e., cupronickel above ternary), including iron cupronickel, manganese cupronickel, zinc cupronickel and aluminum cupronickel. In complex cupronickel, the second major element symbol and the number set of components other than the copper content indicate the content of each element.

For example, BMN3-12 indicates that the nickel content is about 3% and the manganese content is about 12%.

Complex cupronickel is available in 4 models:

Iron cupro: There is a model number. The amount of iron added in iron cupronickel does not exceed 2% to prevent corrosion cracking, which is characterized by high strength, and the ability to resist corrosion, especially the corrosion of flowing seawater, can be significantly improved.

Manganese cupro: model BMN3-12. Manganese cupronickel has a low temperature coefficient of resistance, can be used in a wide temperature range, has good corrosion resistance, and also has good processability.

Zinc cupro: BZN18-18, BZN18-26, BZN15-12 (ZN). Zinc white copper has excellent comprehensive mechanical properties, excellent corrosion resistance, good formability of cold and hot processing, easy to cut, can be made into wires, bars and plates, used in the manufacture of precision parts in the fields of instruments, meters, daily necessities and other fields.

Aluminum cupro: the model has BAL13-3. It is an alloy formed by adding aluminum based on copper-nickel alloy, and the density is.

The alloy properties are related to the ratio of the amount of nickel and the amount of aluminum in the alloy, and when Ni:Al=10:1, the alloy properties are good.

Commonly used aluminum cupronickel includes, Cu13Ni3Al, etc., which are mainly used for various high-strength corrosion-resistant parts such as shipbuilding, electric power, and chemical industry.

Ordinary cupronickel: A copper-nickel binary alloy (i.e., binary cupronickel) is called ordinary cupronickel. In ordinary cupronickel, the letter B indicates the amount of nickel added, e.g., B5 indicates that the nickel content is about 5%, and the rest is about the copper content. There is a model number.

Industrial cupronickel: Industrial cupronickel is divided into two categories: structural cupronickel and cupronickel for precision resistance alloys (electrical cupronickel).

The general composition is 60 copper, 20 nickel and 20 zinc. The nickel content is about 10% to 30%. Alloys with higher nickel content are known as constantan.

Cupronickel is a copper-based alloy with nickel as the main added element. It is silvery-white in color and has a metallic luster, hence the name. Nickel can be infinitely solid soluble with each other, thus forming a continuous solid solution, i.e. it is always a single-phase alloy regardless of its ratio to each other.

When nickel is melted into copper, which contains more than 16%, the resulting alloy becomes as white as silver. The higher the nickel content, the whiter the color. The nickel content in copper is generally 25%.

White dragon is an alloy composed mainly of copper and nickel. White Dragon is a copper-based alloy with nickel as the main additive. It is silvery-white in color and has a metallic luster, hence the name.

Nickel can be infinitely solid soluble with each other, thus forming a continuous solid solution, i.e. it is always a single-phase alloy regardless of its ratio to each other.
