Features and potential applications of C71300 white copper: This structural copper-nickel alloy has excellent mechanical qualities, resistance to corrosion, and good processing under pressure in both hot and cold conditions.

Classification of white copper and copper alloys:

1: Nickel-nickel copper: Adding pure copper to nickel can significantly improve the strength, corrosion resistance, resistance and thermoelectric properties of copper alloys.

The automotive, shipbuilding, resistance wire, thermocouple, and seawater desalination and heat exchange systems industries are the primary uses for white copper. Industrial white copper is classified into two categories: structural white copper and electrical white copper, which fulfill different requirements for corrosion resistance and unique electrical and thermal qualities. These categories are based on the performance characteristics and usage of the respective types of white copper. A common corrosion-resistant and beautiful structural material is white copper wire. It is used to manufacture corrosion-resistant elastic components, medical equipment, everyday decorations, and electromechanical, chemical, and instrumentation gear in industrial industries.

The primary drawback of white copper is the higher cost and scarcity of nickel, a crucial metal. Nickel serves as the primary alloying element in white copper, a copper alloy. Regardless of their proportions, solid solutions containing nickel and copper can be indefinitely dissolved in the α-single phase. Additionally, there are two types of cupronickel: common cupronickel, or copper-nickel binary alloy, and special cupronickel, which is made with the addition of other alloying elements like iron, zinc, and manganese.

2. Regular white copper has a face-centered cubic lattice and is a continuous solid solution made of copper and nickel. The composition-temperature range for metastable breakdown is fairly broad when the temperature is below 322 degrees. In copper-nickel alloys, the addition of third elements such as Fe, Cr, Sn, Ti, Co, Si, Al, etc. can alter the metastable Certain alloy qualities can also be enhanced by the composition-temperature range and decomposition location. White copper finds significant use in high-resistance alloys and thermocouple alloys, in addition to structural applications. Ordinary white copper comes in the following primary grades: B0.6, B5, B19, B25, and B30.

3. Aluminum White Copper: The alloy's performance is contingent upon the proportion of aluminum to nickel. The best alloy performance occurs when Ni: Al=10:1. Aluminum white copper is primarily utilized in the shipbuilding, electric power, chemical, and other industrial sectors for a variety of high-strength, corrosion-resistant parts.

4. Zinc-nickel copper: It is easy to cut, has good formability in both hot and cold processing, and has great comprehensive mechanical qualities. It also has strong corrosion resistance. It is used to make instruments, meters, medical equipment, everyday requirements, and communications. It may also be formed into wires, bars, and plates. parts with precision in other disciplines.

5. The fifth type of copper is manganese white copper, which has excellent corrosion resistance, a low-temperature coefficient of resistance, a wide temperature range of use, and good processability. Performance: 1221.7°C solid point, 1291.8°C liquid point.

Among cupronickel, zinc cupronickel is a significant variation. It performs well in processes, has outstanding mechanical qualities, and is a stunning silvery white color. It's a well-known artistic copper alloy replica of silver. 15% nickel and 15% zinc are its usual constituents. Several nations frequently employ 20% BZn15-20 alloy to create a variety of handicrafts. This alloy was dubbed "Chinese Silver" during the Song Dynasty in my nation and was utilized to create extremely sophisticated handicrafts. Zinc-nickel copper has been utilized as a crucial plug-in component and in electromagnetic shielding shells for a variety of electronic equipment, including crystal oscillator tube shells, since the advancement of modern communication technology.

The engineering community has typically raised the nickel percentage in BZn15-20 alloy to improve its mechanical qualities, corrosion resistance, and silvery color; this has led to the creation of new alloys like BZn18-8 and BZn18-26. Lead-nickel copper—copper added to zinc-nickel copper—is mostly used to create mirror frame accessories, precision instrument parts, and other items by improving the machinability of zinc-nickel copper.

Application fields: Copper alloys used in manufacturing heat exchangers and condensers in industrial sectors such as shipbuilding and electric power.
The functions of each alloying element in copper alloy:
① Zinc (Zn): Zinc has a large solid solubility in the alloy and has solid solution strengthening effect.
② Nickel (Ni): Improves the strength, toughness and resistance to dezincification and stress corrosion cracking of the alloy.
③ Lead (Pb): Enhances lubricity, improves wear resistance and improves cutting processability. The chips are brittle and the surface of the workpiece is smooth.
④Aluminum (Al): Improves corrosion resistance, thermal stability and strength, but brittleness will occur when excessive (more than 1%-2%).
⑤Manganese (Mn): Improves corrosion resistance, thermal stability and strength, but brittleness will occur when excessive (more than 1%-2%).
⑥Magnesium (Mg): Trace amounts of magnesium reduce the conductivity of copper, improve copper's high-temperature oxidation resistance, and also have a deoxidizing effect on copper.
⑦Tin (Sn): It inhibits dezincification and improves corrosion resistance, especially the ability to resist seawater corrosion. Therefore, tin brass is called "Navy Brass".
⑧Copper (Cu): Good chemical stability, high strength, easy to weld, corrosion resistance, plasticity, ductility, high thermal conductivity and electrical conductivity.
⑨Iron (Fe): Iron that exceeds solid solubility exists as iron-rich phase particles. It has a high melting point and can serve as crystal nuclei to refine grains and prevent recrystallized grains from growing, thereby improving the mechanical properties and process performance of the alloy.
⑩Silicon (Si): Improves strength and hardness, casting fluidity, and weldability, but the plasticity is reduced. For example, adding Si and Pb at the same time can reduce the friction factor.
