Better for what? Usually one material is better for some things, other materials for other things. The special feature of constantan is its low temperature coefficient for electrical resistance.

What is a copper-constantan thermocouple?

A thermocouple is a temperature sensor made from two different types of metal. Different metal types give different sensing properties and ranges. Several standard pairs of metals are defined in industry and designated by a letter. A copper-constantan thermocouple is "Type T."


Why is a copper saucepan better than iron?

Copper pans are not necessarily better, but copper certainly conducts heat a lot better than iron.


Is nickel a better conductor than copper?

Does a copper heat sink or an aluminum one with a base made of copper work any better than a pure aluminum one?

The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.


Why is copper better than rubber to hold electricity?

Copper is a better conductor of not only electricity, but also heat. This is because copper is a metal.


Is stranded copper wire a better conductor than solid copper wire?

no


Which is best copper or zinc?

copper and zinc both are conductive materials but as copper is in lower position than zinc in electromotive charts zinc is more than copper but other material properties like corrosive force,strength are better for copper. so for daily use copper is better than zinc.


What is SWG in constantan wire?

SWG stands for Standard Wire Gauge, which is a system of measuring the diameter of wire. In constantan wire, SWG indicates the thickness or gauge of the wire, with a higher SWG number correlating to a thinner wire diameter. Constantan is a copper-nickel alloy known for its low thermal coefficient of resistance, making it useful in applications where consistent electrical properties are required over a wide temperature range.


How steel conduct more heat than copper?

That is NOT correct. Copper conducts heat better than steel.
