mangaanin
Mangaanin, more commonly spelled manganin, refers to a copper-based alloy composed primarily of copper with manganese and nickel added in small amounts. The typical composition is about 84% copper, with roughly 12% manganese and 4% nickel, though exact formulations vary by manufacturer. The alloy is valued for its relatively high resistivity among copper alloys and for its exceptionally low and stable temperature coefficient of resistance, making it useful in precision electrical applications.
The key property of manganin is its resistance stability over a wide range of temperatures. Unlike pure
Manufacture involves melting and alloying copper with manganese and nickel, followed by forming and annealing to
Applications of manganin have historically included resistance standards, precision shunts, and temperature-stable resistors in laboratory instrumentation.
