What are the functions of copper-nickel alloys

What color is copper nickel?
The variable current laser ion beam gas phase method can prepare highly uniform mixed nano nickel-copper alloy powder with controllable particle size and Cu-Ni composition, with high purity, uniform particle size, spherical shape, good dispersion, small sintering shrinkage, and black powder.

Why is nickel added to copper?
The addition of nickel to copper can increase strength and corrosion resistance while maintaining toughness of the alloy. Other elements can be added to the copper-nickel alloy to improve strength, corrosion resistance, hardenability, weldability and castability. The corrosion-resistant copper-nickel alloy contains about 30% nickel, and a small amount of iron and manganese, and their properties in salt water are particularly stable.

What is the use of nickel-copper alloy?
Non-marine applications of copper and nickel include cryogenic applications, brake tubing and silver coins, such as 1 Euro and 2 Euro coins and 5 cents of nickel. Due to its strong antibacterial properties, copper-nickel alloys are used as hygienic "contact materials" to reduce cross-contamination and infection, especially in hospital intensive care units. In addition, copper and nickel can also be used
1. Copper or nickel-based alloy powder metallurgy
2. Seawater resistant materials with surface coatings for ships
2. Wear-resistant lubricants, wear-resistant additives
4. Electrically conductive and thermally conductive filler materials
5. Electromagnetic shielding materials
6. Manufacturing multilayer ceramic capacitor terminals and internal electrodes, electronic components, electronic pastes, etc.
7. Ocean Engineering
8. Swiss franc
9. Other uses

Is nickel-copper alloy magnetic?
Although the diamagnetism of copper is very weak, it needs 0.8% or 0.9% nickel to neutralize this diamagnetic effect, and 56% nickel is required before the alloy exhibits ferromagnetic properties at room temperature. Can nickel be dissolved in copper? Nickel can be completely dissolved in copper, allowing a variety of alloy compositions. Copper-nickel alloy is strong and has strong plasticity. The addition of nickel to copper (usually 2-30%) can make the metal highly resistant to corrosion and has excellent electrical conductivity.
