Copper Based Manganin Alloy Strip / Wire 6J11
Manganin is an alloy of copper, manganese, and nickel. It was created by Edward Weston in 1892 as an improvement to his previous alloy, Constantan. Manganin has moderate resistivity and a low temperature coefficient. It is commonly used to manufacture resistors, particularly ammeter shunts, due to its stable resistance value and virtually zero temperature coefficient. Manganin wire is also used as an electrical conductor in cryogenic systems to minimize heat transfer. It served as the legal standard for the ohm in the United States from 1901 to 1990.
Manganin foil and wire are highly sought after materials in the production of resistors, especially ammeter shunts. This is due to their exceptional properties of virtually zero temperature coefficient of resistance value and long-term stability. These materials are essential components in the manufacturing of electrical products.
Copper-based low resistance heating alloy is another widely used material in the low-voltage electrical industry. It is a key component in the production of low-voltage circuit breakers, thermal overload relays, and other similar electrical products. Our company produces high-quality materials that exhibit excellent resistance consistency and superior stability. We offer a wide range of round wire, flat, and sheet materials to cater to the diverse needs of our customers.

Characteristic
Pure copper plus nickel can significantly improve strength, corrosion resistance, hardness, electrical resistance and pyroelectricity, and reduce the temperature coefficient of resistivity. Therefore, the mechanical and physical properties of white copper are exceptionally better than other copper alloys.
Good ductility, high hardness, beautiful color, corrosion resistance and deep drawing performance, are widely used in shipbuilding, petrochemical, electrical appliances, instruments, medical machinery, daily necessities, handicrafts and other fields, and are also important resistance and thermocouple alloys. The disadvantage of cupronickel is the main added element - nickel is a scarce strategic material, and the price is relatively expensive.
