There are many constantan wire manufacturers, and a search on the Internet will reveal a large number of manufacturers, but the production methods or processes of each company are not exactly the same, and different quality of constantan wire will appear. The constantan wire produced by our factory has an absolute advantage over general manufacturers in terms of quality. Our company strictly conducts constantan wire selection, refining, cold drawing, medium thick wire, secondary refining, etc. All operation steps are strictly carried out, and random inspections are carried out to ensure that the quality of constantan wire is fully qualified. Only then was allowed to flow to the market to the customer.
Let us first understand the constantan wire: Constantan wire is a resistance alloy with copper and nickel as the main components. Constantan has a lower temperature coefficient of resistance (α< ±40×10-6/℃). It has good corrosion resistance, welding performance and processing performance characteristics. Product classification and physical properties: It can be used as general resistance elements, rheostats, wirewound potentiometers, resistances for AC precision instruments, low-temperature heating resistors (<500°C), etc. Shunt-type manganese-copper alloy has low temperature coefficient of resistance, low thermoelectric potential and high resistivity. It can be used as additional resistance and shunt resistance on general electronic instruments and electric meters. The operating temperature range is 0-100℃.
Constantan wire has the following characteristics:
1. Constantan wire has a low temperature coefficient of resistance;
2. Good processing performance, corrosion resistance, easy brazing;
3. Various standard resistors, precision or common resistance components can be made.
The quality difference of constantan wire is due to its widespread existence in the market. The main reason is the manufacturer's selection of materials and the manufacturer's level of technology and equipment for constantan wire. In the end, the quality of the finished constantan wire is determined. The use of constantan wire in heating elements cannot be underestimated. High-quality constantan wire can ensure balanced operation in its working environment and a long life, while inferior constantan wire not only does not guarantee its quality, but also in the use of equipment, the damage of constantan wire will cause damage to the equipment and affect its finished products. Quality and honor of the company.
