Manganese Copper Electric Resistant Wire Good Stability For Emitter Resistor
Product Description:
Manganin alloy is one kind of electric resistance alloy which is mainly made of copper, manganese and nickel.
It has character of small resistance temperature coefficient,low thermal EMF vs copper E,outstanding long-term stability,good weldability and workability,which makes it to be superior precision surveying instrument.such as resistor measure voltage/current/resistance and more.
It is also high-quality electric heating wire for low-temperature heating element,such as heater of air-conditioning system,household heating appliances.
Manganin is a trademarked name for an alloy of typically 84% copper, 12% manganese and 4% nickel.
Manganin foil and wire is used in the manufacture of resistors, particularly ammeter shunts, because of its virtually zero temperature coefficient of resistance value and long term stability. Several Manganin resistors served as the legal standard for the ohm in the United States from 1901 to 1990. Manganin wire is also used as an electrical conductor in cryogenic systems, minimizing heat transfer between points which need electrical connections.
Manganin is also used in gauges for studies of high-pressure shock waves (such as those generated from the detonation of explosives) because it has low strain sensitivity but high hydrostatic pressure sensitivity.
