1. Different Ingredients Nickel chromium alloy wire is mainly composed of nickel (Ni) and chromium (Cr), and may also contain small amounts of other elements. The content of nickel in nickel-chromium alloy is generally about 60%-85%, and the content of chromium is about 10%-25%. For example, the common nickel-chromium alloy Cr20Ni80 has a chromium content of about 20% and nickel content of about 80%. The main component of copper wire is copper (Cu), whose purity can reach more than 99.9%, such as T1 pure copper, copper content as high as 99.95%.   2. Different Physical Properties Color - Nichrome wire is usually silver gray. This is because the metallic luster of nickel and chromium is mixed to give this color. - The copper wire color is purplish red, which is the typical color of copper and has a metallic luster. Density - The linear density of nickel-chromium alloy is relatively large, generally around 8.4g/cm³. For example, 1 cubic meter of nichrome wire has a mass of about 8400 kg. - The copper wire density is about 8.96g/cm³, and the same volume of copper wire is slightly heavier than nickel-chromium alloy wire. Melting Point -Nickel-chromium alloy has a high melting point, around 1400 ° C, which makes it able to work at higher temperatures without melting easily. -The melting point of copper is about 1083.4℃, which is lower than that of nickel-chromium alloy. Electrical Conductivity -Copper wire conducts electricity very well, in standard condition, copper has an electrical conductivity of about 5.96×10 guess S/m. This is because the electronic structure of copper atoms allows it to conduct current well, and it is a commonly used conductive material, which is widely used in fields such as power transmission. Nickel-chromium alloy wire has poor electrical conductivity, and its electrical conductivity is much lower than that of copper, about 1.1×10⁶S/m. This is due to the atomic structure and interaction of nickel and chromium in the alloy, so that the conduction of electrons is hindered to a certain extent. Thermal conductivity -Copper has excellent thermal conductivity, with a thermal conductivity of about 401W/(m·K), which makes copper widely used in places where good thermal conductivity is required, such as heat dissipation devices. The thermal conductivity of nickel-chromium alloy is relatively weak, and the thermal conductivity is generally between 11.3 and 17.4W/(m·K).   3. Different Chemical Properties Corrosion Resistance Nickel-chromium alloys have good corrosion resistance, especially in high temperature oxidation environments. Nickel and chromium form a dense oxide film on the surface of the alloy, preventing further oxidation reactions. For example, in high temperature air, this layer of oxide film can protect the metal inside the alloy from further corrosion. - Copper is easily oxidized in air to form a vercas (basic copper carbonate, formula Cu₂(OH)₂CO₃). Especially in a humid environment, the surface of copper will gradually be corroded, but its corrosion resistance in some non-oxidizing acids is relatively good. Chemical Stability - Nichrome alloy has high chemical stability and can remain stable in the presence of many chemicals. It has a certain tolerance to acids, bases and other chemicals, but it can also react in strong oxidizing acids. - Copper in some strong oxidants (such as nitric acid) under the action of a more violent chemical reaction, the reaction equation is (3Cu + 8HNO₃(dilute)=3Cu(NO₃ +2NO↑ + 4H₂O). 4. Different Uses - nickel-chromium alloy wire - Due to its high resistivity and high temperature resistance, it is mainly used to make electric heating elements, such as heating wires in electric ovens and electric water heaters. In these devices, nichrome wires are able to efficiently convert electrical energy into heat. - It is also used in some occasions where mechanical properties need to be maintained in high temperature environments, such as the support parts of high temperature furnaces. - Copper wire - Copper wire is mainly used for power transmission, because its good electrical conductivity can reduce the loss of electrical energy during transmission. In the power grid system, a large number of copper wires are used to make wires and cables. - It is also used to make connections for electronic components. In electronic products such as computers and mobile phones, copper wires can realize signal transmission and power supply between various electronic components.

1. Electronics industry    As a conductive material, in the manufacture of electronic components, nickel wire is used to connect various electronic components because of its good electrical conductivity. For example, in electronic devices such as integrated circuits and printed circuit boards, nickel wires can be used as conductors to achieve the transmission of electronic signals.    Compared with traditional copper wire, nickel wire has a higher melting point and better oxidation resistance, can work stably in a higher temperature environment, and is suitable for some electronic equipment with high working temperature requirements.    For example, in some precision electronic instruments, communication equipment and medical equipment, nickel wire shielding can improve the stability and reliability of the equipment.   2. Battery field     Lithium battery manufacturing, in lithium-ion batteries, nickel wire can be used as one of the electrode materials of the battery. For example, in nickel-cobalt-manganese ternary lithium batteries (NCM) and nickel-cobalt-aluminum ternary lithium batteries (NCA), the content of nickel plays a key role in the performance of the batteries.     Nickel-metal hydride batteries, nickel wires are used as electrode materials in nickel-metal hydride batteries to achieve the storage and release of electrical energy through a reversible reaction with hydrogen.     Nickel-metal hydride batteries have high capacity and good cycle life, and are widely used in hybrid electric vehicles, power tools and other fields. The quality and performance of nickel wire directly affect the performance and reliability of nickel metal hydride batteries.   3. Aerospace     Engine parts.

For example, nickel-based superalloys have excellent high temperature strength, oxidation resistance and corrosion resistance, and are able to work in high temperature, high pressure and harsh environments.     Avionics, the aerospace field has high reliability requirements for electronic equipment. Nickel wire is widely used in the manufacture of avionics equipment because of its good conductivity, stability and oxidation resistance.    For example, in aircraft navigation systems, communication systems and flight control systems, nickel wires can be used as wires and connecting elements to ensure the stable transmission of electronic signals.   4. Chemical industry    Nickel, the catalyst carrier, has good catalytic performance and is widely used as catalyst in chemical production. Nickel wire can be used as a catalyst carrier, providing a large surface area and good dispersion, improve the activity and stability of the catalyst.    For example, in the fields of petrochemical, fine chemical and environmental protection, nickel wire supported catalysts can be used to catalyze hydrogenation, dehydrogenation, oxidation and other reactions.    Corrosion-resistant materials, in the chemical production process, many equipment and pipelines need to withstand the erosion of corrosive media. Nickel wire can be used to make corrosion-resistant alloy materials to improve the service life and safety of equipment.    For example, in the chemical, pharmaceutical and food processing industries, nickel alloy containers and pipes are widely used to store and transport corrosive substances.   5. Other areas    Jewelry manufacturing, nickel wire has a certain luster and corrosion resistance, in jewelry manufacturing can be used as an auxiliary material or used to make some special jewelry.    For example, nickel wire can be used to weave jewelry such as bracelets and necklaces, and can also be combined with other metal materials to create a unique design effect.   Welding material, nickel wire can be used as welding material, for welding nickel alloy, stainless steel and other metal materials.   Nickel based welding material has good welding performance and corrosion resistance, which can ensure the quality and reliability of welded joints.
