Nickel Chromium Precision Resistance Alloy Wire (YB/T5260-1993)
Nickel Chromium precision resistance alloy wire, also known as Nickel Chrome (NiCr) wire, is a high-quality type of resistance wire made of metal alloy with positive temperature coefficient characteristics (PTC). It is manufactured in accordance with Shanghai YB/T5260-1993, a national standard set by the China Wire and Cable Standardization Technical Committee. The main component material of Nickel Chromium precision resistance alloy wire is Nickel (Ni) and Chromium (Cr), and the main component ratios of Nickel and Chromium are expressed by their chemical symbol such as NiCr13, NiCr20 and so on.
The application of Nickel Chromium precision resistance alloy wire mainly includes some large-scale industrial high-precision automated equipment, electronic equipment, electronic components, automotive engineering and other application fields. This is because Nickel Chromium precision resistance alloy wire has many advantages, such as being resistant to electricity, having high temperature resistance, strong oxidation and corrosion resistance and good heat stability, making it suitable for high-temperature and high-end occasions.
In order to ultilize the superior performance of Nickel Chromium precision resistance alloy wire, its manufacturing process must be strictly controlled. During the manufacturing and surface treatment processes, the conditions should include complete heat treatment of the raw material wire, surface treatment applied uniformly and properly, and rigorous quality control tests. The Nickel Chromium precision resistance alloy wire produced must meet the inspection requirements of various technical indicators in the standard and ensure that it is not rusty, has no burrs and falls into the defect inspection range specified by the standard.
To ensure that Nickel Chromium precision resistance alloy wire can work normally and with high reliability in different application scenarios, after the raw material wire and surface treatment processes, rigorous inspection and comprehensive tests must be performed. According to the national standard requirements and manufacturers inspection items, the inspection items of Nickel Chromium precision resistance alloy wire must be conducted including chemical composition analysis, artificial aging resistance, pre-treatment of electric heating, salt spray test and high temperature heat aging resistance test , etc. The results of these tests will be used to determine whether the Nickel Chromium precision resistance alloy wire meets the above requirements and whether it is suitable for its intended purpose.
Overall, Nickel Chromium precision resistance alloy wire is a type of high-quality resistance wire with excellent properties. By following the national standard and strictly controlling the manufacturing process, Nickel Chromium precision resistance alloy wire can normally ensure its function and performance in different application scenarios, bringing real and reliable value to the end user.
