Question

write the constituents of constantan , manganin and nichrome ​

Answer 1

Explanation:

• Constantan is a copper–nickel alloy also known as Eureka, Advance, and Ferry. It usually consists of 55% copper and 45% nickel. ... Other alloys with similarly low temperature coefficients are known, such asmanganin (Cu [86%] / Mn [12%] / Ni [2%] ).
• Manganin is a trademarked name for an alloy of typically 84% copper, 12% manganese, and 4% nickel.
• A common nichrome alloy is 80% nickel and 20% chromium, by mass, but there are many other combinations of metals for various applications. Nichrome is consistently silvery-grey in colour, is corrosion-resistant, and has a high melting point of about 1,400 °C (2,550 °F).
