Manganin is an alloy of manganese and copper that typically contains 12% to 15% manganese and a small amount of nickel. Manganese copper is a unique and versatile alloy that is popular in various industries for its excellent properties and wide range of applications. In this article, we will discuss its composition, properties, and the many ways it is used in modern technology.

Composition and properties of manganese copper

Manganese copper is a copper-nickel-manganese alloy known for its low temperature coefficient of resistance (TCR) and high electrical resistance. The typical composition of manganese copper is approximately 86% copper, 12% manganese and 2% nickel. This precise combination of elements gives the material excellent stability and resistance to temperature changes.

One of the most notable properties of manganese copper is its low TCR, meaning that its resistance changes very little with temperature fluctuations. This property makes copper-manganese an ideal material for applications requiring accurate and stable electrical measurements, such as resistors and strain gauges. Additionally, manganese copper has high electrical conductivity, making it suitable for use in a variety of electrical and electronic equipment.
