Brief introduction of nickel-chromium alloy
Jul 30, 2021
Chromium alloy has high strength and corrosion resistance, and the alloy composed of iron and nickel is commonly known as stainless steel.
Commonly used in cutting tools; spraying, deposition and high-temperature diffusion methods are used to form corrosion-resistant alloy layers on the surface of steel or iron; potassium dichromate and sodium dichromate are strong oxidants in organic synthesis and the petroleum industry; chrome yellow, Chrome orange, chrome green, etc. can be used as inorganic pigments.
The coloring substance in the alcohol test used by traffic police is dichromate. Alcohol can interact with it to make it color.
Nickel-chromium alloys can also be used to make laboratory resistors.
High-resistance electric heating alloys (high nickel and iron-chromium-aluminum), high-temperature alloys, precision alloys, heat-resistant alloys, special alloys, stainless steel, etc. are all common and commonly used nickel-chromium alloys.
When the length and cross-sectional area are constant, the lower the temperature, the greater the resistance of the nickel-chromium alloy, which is contrary to the general law.
Nickel-chromium alloys are also widely used in the vacuum coating industry, and can be made into a certain proportion of alloy targets as raw materials for magnetron sputtering coating.
