About Copper Nickel Cu–Ni Alloy powder:
Physical properties: Copper-nickel alloy powder is silver-white with a metallic luster, and its density is usually about 8.9g/cm³, slightly higher than the density of pure copper. It has good electrical and thermal conductivity and can be used to manufacture the substrate and shell of electronic components.
Chemical properties: Copper-nickel alloy powder is a kind of active metal material that is easy to react with oxygen and water to produce oxides and hydroxides. At high temperatures, it is also easy to respond with non-metallic elements, such as silicon, carbon, etc., to generate corresponding compounds. Therefore, special attention must be paid to prevent contact with oxygen and water during preparation and use.
Mechanical properties: Copper-nickel alloy powder has good mechanical properties, and its tensile strength, yield strength and hardness are higher than pure copper and pure nickel. In addition, it also has good wear resistance and corrosion resistance.
Thermal properties: Copper-nickel alloy powder has good thermal conductivity and thermal diffusivity, so it has many applications in electronics and aerospace. In addition, it has a high melting point and is not easy to melt, which can be used to manufacture high-temperature components and structural parts.
Processing performance: Copper-nickel alloy powder has good processing performance and can be made into various shapes and sizes of parts through calendering, forging, extrusion and other processes. In addition, it can be further optimized through coating treatment, composite material manufacturing and other techniques.

How are Copper Nickel Cu-Ni Alloys Powdermade? Atomization method: Atomization method atomizes molten copper and nickel alloy into fine particles through high-pressure gas. In the atomization process, the molten copper and nickel alloys are sprayed through the nozzle and impacted and cooled by the high-pressure gas to form a fine alloy powder. The copper-nickel alloy powder with uniform composition and fine particle size can be obtained by this method, but the production cost is high.
Mechanical alloying method: The automated alloying way is mixing copper and nickel metal powder and preparing alloy powder using high-energy ball milling. In the ball milling process, the metal powder of copper and nickel constantly collides and frictions in the ball mill, gradually forming alloy powder. The copper-nickel alloy powder with uniform composition and fine particle size can be prepared by mechanical alloying. Still, the production cycle is long and high-energy ball milling equipment is needed.
Chemical method: The chemical method converts a compound of copper and nickel into an alloy powder through a chemical reaction. For example, chlorides or oxides of copper and nickel are reacted with reducing agents (such as hydrogen) to synthesize alloy powders at high temperatures. Copper-nickel alloy powder with uniform composition and fine particle size can be prepared by chemical method, but chemical reagents and high-temperature equipment are needed.
Electrochemical method: The electrochemical process prepares alloy powder by electrolyzing copper and nickel salt. During electrolysis, cations of copper and nickel are precipitated on the cathode and form an alloy powder. The electrochemical method can prepare copper-nickel alloy powder with uniform composition and fine particle size. Still, it must use electrolytic equipment and salt solution with high water quality requirements.
