NiCr Alloy

NiCr alloy is a nickel-chromium alloy, which is mainly composed of nickel and chromium, and may contain other elements such as iron, silicon, cerium, etc. The specific composition ratio can be adjusted according to the application requirements. This alloy has excellent high-temperature properties, oxidation resistance, corrosion resistance and wear resistance, so it is widely used in many fields. Below are some of the main applications and characteristics of NiCr alloys.

Application Areas.
In the vacuum coating industry, NiCr alloy targets and films are widely used as surface protection films for wear, corrosion and heat resistance, as well as resistive films, which are involved in low-E glass, microelectronics, magnetic recording, semiconductors and thin film resistors and other different fields.
Nickel-chromium-iron alloys (e.g., NiCr28FeSiCe) are high-temperature alloys that are mainly used as materials for high-temperature environments and have excellent high-temperature, oxidation corrosion and wear resistance. This alloy plays an important role in China's aerospace, aviation, petrochemical, energy and other fields4.
Characteristics.
Nickel-chromium alloy has excellent oxidation and corrosion resistance, adapts to a wide range of temperature changes, and is applied to the surface of the film layer or workpiece to protect the film layer and workpiece.
Resistive films using NiCr alloy as the source material are characterized by high resistivity, low resistance temperature coefficient, high sensitivity coefficient, and small temperature dependence. Because of the mature preparation process, stable performance, and long history of use, Nichrome resistive films are widely used!
